		40	4.53 Tue Aug 14 11:27:50 CEST 2018
		41	- add $Config{libs} to LIBS for configure, to work around systems
		42	with broken library dependencies (... openbsd).
		43
		44	4.52 Sun Aug 12 08:09:45 CEST 2018
		45	- config.h.in was missing in distribution.
		46
		47	4.51 Sun Aug 12 07:24:14 CEST 2018
		48	- complete rework of the autoconf framework: IO::AIO now uses its own
		49	config.h, separate from libeio, and tries to test the actual perl
		50	environment, not the standard system environment.
		51	- provide nanosecond-accracy stat time accessors for both perl and IO::AIO
		52	stat functions.
		53	- removed non-portable C++ syntax from eio.c.
		54	- try to fix readdir tests on cygwin spuriously failing.
		55
		56	4.5 Wed Aug 1 00:23:55 CEST 2018
		57	- aio_mtouch touch all pages as requested, not just the first page in most cases.
		58	- new function: IO::AIO::mremap, linux-specific mremap, with constants MREMAP_MAYMOVE

		60	- add O_ACCMODE.
		61	- add (undocumented) MSG_CMSG_CLOEXEC and SOCK_CLOEXEC constants.
		62
		63	4.4 Tue Feb 20 07:54:12 CET 2018
		64	- new aio_slurp request.
		65	- add (experimental) IO::AIO::eventfd and timerfd* function.
		66	- add (experimental) IO::AIO::get_fdlimit and IO::AIO::min_fdlimit.
		67	- point out that aio_copy overwrites existing files.
		68	- removed filesystem magic number table from aio_statvfs docs as
		69	statvfs doesn't actually return this info at all (statfs does).
		70	- add a bunch of (mostly linux-specific) constants for use in ioctls
		71	(see aio_ioctl docs).
		72	- treescan now has a proper manpage and useful --help output.
		73	- new option --sync in treescan, to sync everything in a subtree.
		74	- changed default for aio_msync flags to MSYNC_SYNC.
		75	- document offset/length behaviour of mprotect/madvise.
		76	- support linux's renameat2 (via aio_rename2).
		77	- add aio_rename2, an aio_rename with flags.

		79	- add FALLOC_FL_INSERT_RANGE, FALLOC_FL_UNSHARE_RANGE.
		80	- (libeio) use posix_close if available.
		81	- (libeio) internal close() calls no longer disturb errno.
		82	- add IO:AIO::FALLOC_FL_UNSHARE.
		83	- update schmorp.h for removal of USE_SOCKETS_AS_HANDLES
		84	and better eventfd detection.
		85
		86	4.34 Sun May 1 19:18:24 CEST 2016
		87	- def0.h was not properly generated during previous release, causing
		88	compile errors on various platforms.
		89	- major/minor were accidentally switched (reported by Alexander Lishenyuk).
		90	- removed duplicate definition of MAP_HUGETLB, that was found due to
		91	a bug in Perl::Tidy (testcase by alaska332@gmail.com).
		92	- added (untested!) aio_fcntl, aio_ioctl requests.
		93	- (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
		94	as manpages-dev originally claimed.
		95
		96	4.33 Mon Jan 18 12:50:10 CET 2016

		101	- added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
		102	consdtants, whether they can be sensibly used or not.
		103	- use NO_INIT where applicable.
		104	- update libecb.
		105	- added stability canary support.
		106	- updated linux super magic table to 4.3.3.
		107
		108	4.32 Wed Feb 11 20:32:11 CET 2015
		109	- replace off_t by STRLEN where appropriate, should not result in
		110	user-visible changes.
		111	- update ecb.h for C11 compatibility.
		112
		113	4.31 Tue Jun 3 03:29:27 CEST 2014
		114	- work around more 5.20 bugs. backwards compatibility my ass.
		115
		116	4.3 Fri Apr 11 06:22:38 CEST 2014
		117	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		118	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		119	in 5.18. What's so attractive about giving a shit about backwards
		120	compatibility - I will never understand.
		121
		122	4.2 Sat Jan 25 01:13:14 CET 2014
		123	- aio_group could corrupt memory because it didn't restore

		130	- (libecb) insignificant update.
		131
		132	4.19 Sun Jan 6 12:47:26 CET 2013
		133	- avoid endless loop in fiemap with some XFS files.
		134	- in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
		135	and call rename/rmdir instead of renameat/unlinkat.
		136
		137	4.18 Thu Oct 11 07:01:26 CEST 2012
		138	- fix unintended xthread_create by intentionalising it :)
		139
		140	4.17 Thu Oct 11 05:19:47 CEST 2012
		141	- rename aio_fallocate to aio_allocate, to match documentation.
		142	- add list of linux fsid values to aio_statvfs docs.
		143	- work around a bug in btrfs' FIEMAP ioctl implementation.
		144	- work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
		145	as per unix spec.
		146
		147	4.16 Tue Aug 14 05:39:03 CEST 2012
		148	- aio_statvfs was wromgly marked for wd emulation, causing

		150	- fix a crash in aio_fiemap, when used on ranges without any
		151	extents.
		152	- work around linux kernel bug (at least in 3.2): kernel might
		153	trash fiemap input arguments.
		154	- work around linux kernel bug (at least in 3.2): kernel does not
		155	set FIEMAP_EXTENT_LAST on last segment.
		156	- work around linux kernel bug (at least in 3.2): kernel silently
		157	truncates segment count if a file.
		158	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		159	to quick overview.
		160	- splice can corrupt data.
		161	- (libeio) remove pread/pwrite emulation.
		162	- do not grow mmaped scalars in aio_read.
		163	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		164	- provide pread/pwrite for win32, making it link again on native win32.
		165
		166	4.15 Tue Apr 10 06:59:00 CEST 2012
		167	- always include linux/types.h for fiemap, for compatibility to
		168	ancient systems (Paul Howarth).
		169	- experimental support for IO::AIO::splice and ::tee (no aio_...).
		170	- provide SEEK_HOLE and SEEK_DATA, if available.
		171	- work around (again!) an immensely stupid bug in RHEL, defining
		172	autoconf macros in linux system headers (analysed by Paul Howarth).
		173
		174	4.14 Sat Apr 7 02:45:18 CEST 2012
		175	- fix stat structure usage on windows, which caused bogus stat results.
		176	- (libeio) make readahead emulation behave more like actual readahead by never failing.
		177	- new request aio_seek.
		178	- new request aio_fiemap.

		180
		181	4.12 Fri Dec 30 08:51:25 CET 2011
		182	- realpath would return a random value if the name was too long,
		183	instead of -1.
		184	- port to c89.
		185
		186	4.11 Mon Oct 10 00:24:11 CEST 2011
		187	- libeio didn't compile on !linux (Paul Howarth).
		188
		189	4.1 Sun Oct 9 10:24:11 CEST 2011
		190	- IO::AIO did access uninitialised memory on unsuccessful stats.
		191	- (libeio) added syncfs syscall wrapper.

		193	- (libeio) support multiple indepenent working directories.
		194	- applied speling corrections by Nicholas Bamber.
		195	- tune treescan #threads and #outstanding requests a bit.
		196	- reduce the number of file descriptors in use at any one time
		197	in treescan, to avoid running out of them (and using too much ram).
		198	- take advantage of working directoriy abstractions
		199	in aio_scandir and treescan.
		200	- reduce compiled size by ~10% by not inlining some key functionality.
		201	- added --progress switch to treescan.
		202
		203	4.0 Mon Jul 18 05:01:10 CEST 2011
		204	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		205	see FORK BEHAVIOUR in manpage for details.
		206	- passes testsuite on win32 now and may actually work
		207	(activestate 5.10.1 / MSVC6, YMMV).
		208	- (libeio) fix a deadlock where a wakeup signal could be missed when
		209	a timeout occured at the same time.
		210	- (libeio) added realpath.
		211	- (libeio) added fallocate.

		213	- (libeio) do not acquire any locks when forking.
		214	- (libeio) use fewer time() syscalls when waiting for new requests.
		215
		216	3.93 Wed Jun 29 23:44:18 CEST 2011
		217	- ECB.H WAS MISSING.
		218

		221
		222	3.91 Wed Jun 29 13:24:42 CEST 2011
		223	- (libeio) work around a Linux (and likely FreeBSD and other
		224	kernels) bug where sendfile would not transfer all the requested
		225	bytes on large transfers, using a heuristic.
		226	- buggy sendfile caused aio_move/copy to sometimes fail for big
		227	files (fortunately it checks that the whole file has been
		228	transferred...)
		229	- use libecb for higher performance and higher portability.
		230	- (libeio) disable sendfile on darwin, it's too broken.

		233	- document the fact that fork doesn't work anymore when using
		234	this module, on anything !GNU/Linux.
		235	- increase timeout in t/04_fork.t, as too many CPAN-tester setups

		249	3.72 Fri Feb 11 04:25:38 CET 2011
13	- use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock.	250	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
