		39	TODO: aio_fcntl/ioctl test.
		40
		41	- removed duplicate definition of MAP_HUGETLB, that was found due to
		42	a bug in Perl::Tidy (testcase by alaska332@gmail.com).

		44
		45	4.33 Mon Jan 18 12:50:10 CET 2016
		46	- add IO::AIO::pipe2 function.

		48	constants.
		49	- added support for O_TMPFILE and O_PATH constants.
		50	- added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
		51	consdtants, whether they can be sensibly used or not.
		52	- use NO_INIT where applicable.
		53	- update libecb.
		54	- added stability canary support.

		56
		57	4.32 Wed Feb 11 20:32:11 CET 2015
		58	- replace off_t by STRLEN where appropriate, should not result in

		64
		65	4.3 Fri Apr 11 06:22:38 CEST 2014
		66	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		67	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		68	in 5.18. What's so attractive about giving a shit about backwards
		69	compatibility - I will never understand.
		70
		71	4.2 Sat Jan 25 01:13:14 CET 2014
		72	- aio_group could corrupt memory because it didn't restore
		73	the stack after req_submit.

		75	- work around changes in ExtUtils::MakeMaker.
		76	- (libeio) implement aio_realpath for win32.
		77	- (xthread) work around compile time bugs in ptw32.
		78	- added IO::AIO::pipesize.
		79	- (libecb) insignificant update.
		80
		81	4.19 Sun Jan 6 12:47:26 CET 2013
		82	- avoid endless loop in fiemap with some XFS files.
		83	- in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]

		85
		86	4.18 Thu Oct 11 07:01:26 CEST 2012

		94	as per unix spec.
		95
		96	4.16 Tue Aug 14 05:39:03 CEST 2012
		97	- aio_statvfs was wromgly marked for wd emulation, causing
		98	it to malfunction for paths.
		99	- fix a crash in aio_fiemap, when used on ranges without any
		100	extents.
		101	- work around linux kernel bug (at least in 3.2): kernel might
		102	trash fiemap input arguments.
		103	- work around linux kernel bug (at least in 3.2): kernel does not
		104	set FIEMAP_EXTENT_LAST on last segment.
		105	- work around linux kernel bug (at least in 3.2): kernel silently
		106	truncates segment count if a file.
		107	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		108	to quick overview.
		109	- splice can corrupt data.
		110	- (libeio) remove pread/pwrite emulation.
		111	- do not grow mmaped scalars in aio_read.
		112	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		113	- provide pread/pwrite for win32, making it link again on native win32.
		114
		115	4.15 Tue Apr 10 06:59:00 CEST 2012
		116	- always include linux/types.h for fiemap, for compatibility to
		117	ancient systems (Paul Howarth).

		119	- provide SEEK_HOLE and SEEK_DATA, if available.
		120	- work around (again!) an immensely stupid bug in RHEL, defining
		121	autoconf macros in linux system headers (analysed by Paul Howarth).
		122
		123	4.14 Sat Apr 7 02:45:18 CEST 2012
		124	- fix stat structure usage on windows, which caused bogus stat results.
		125	- (libeio) make readahead emulation behave more like actual readahead by never failing.
		126	- new request aio_seek.
		127	- new request aio_fiemap.
		128	- autogenerate the #ifdef/#define 0 blocks for symbols we export.
		129
		130	4.12 Fri Dec 30 08:51:25 CET 2011
		131	- realpath would return a random value if the name was too long,
		132	instead of -1.
		133	- port to c89.
		134
		135	4.11 Mon Oct 10 00:24:11 CEST 2011
		136	- libeio didn't compile on !linux (Paul Howarth).
		137
		138	4.1 Sun Oct 9 10:24:11 CEST 2011
		139	- IO::AIO did access uninitialised memory on unsuccessful stats.
		140	- (libeio) added syncfs syscall wrapper.
		141	- (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
		142	- (libeio) support multiple indepenent working directories.
		143	- applied speling corrections by Nicholas Bamber.
		144	- tune treescan #threads and #outstanding requests a bit.
		145	- reduce the number of file descriptors in use at any one time
		146	in treescan, to avoid running out of them (and using too much ram).
		147	- take advantage of working directoriy abstractions
		148	in aio_scandir and treescan.
		149	- reduce compiled size by ~10% by not inlining some key functionality.
		150	- added --progress switch to treescan.
		151
		152	4.0 Mon Jul 18 05:01:10 CEST 2011
		153	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		154	see FORK BEHAVIOUR in manpage for details.
		155	- passes testsuite on win32 now and may actually work
		156	(activestate 5.10.1 / MSVC6, YMMV).
		157	- (libeio) fix a deadlock where a wakeup signal could be missed when
		158	a timeout occured at the same time.
		159	- (libeio) added realpath.
		160	- (libeio) added fallocate.
		161	- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
		162	- (libeio) do not acquire any locks when forking.
		163	- (libeio) use fewer time() syscalls when waiting for new requests.
		164
		165	3.93 Wed Jun 29 23:44:18 CEST 2011
		166	- ECB.H WAS MISSING.
		167
		168	3.92 Wed Jun 29 14:45:41 CEST 2011
		169	- ecb.h was missing.
		170
		171	3.91 Wed Jun 29 13:24:42 CEST 2011
		172	- (libeio) work around a Linux (and likely FreeBSD and other
		173	kernels) bug where sendfile would not transfer all the requested
		174	bytes on large transfers, using a heuristic.
		175	- buggy sendfile caused aio_move/copy to sometimes fail for big
		176	files (fortunately it checks that the whole file has been
		177	transferred...)
		178	- use libecb for higher performance and higher portability.
		179	- (libeio) disable sendfile on darwin, it's too broken.
		180	- disable fork tests on !linux, as only linux supports mixing
		181	pthread and fork in perl.
		182	- document the fact that fork doesn't work anymore when using
		183	this module, on anything !GNU/Linux.
		184	- increase timeout in t/04_fork.t, as too many CPAN-tester setups
		185	run on a 0.1MHz cpu. Or so.
		186
		187	3.9 Fri May 27 02:43:47 CEST 2011
		188	- (libeio) fix memory corruption in aio_readdirx for the flags
		189	combination READDIR_STAT_ORDER \| READDIR_DIRS_FIRST.
		190	- add lots of newer POSIX and GNU/Linux-specific open
		191	flags.
		192
		193	3.8 Sun Mar 27 12:25:33 CEST 2011
		194	- use nonstandard but maybe-working-on-bsd fork technique.
		195	- support a max_idle value of 0.
		196	- support setting of idle timeout value (IO::AIO::idle_timeout).
		197
		198	3.72 Fri Feb 11 04:25:38 CET 2011
		199	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
		200	- aio_mknod always used a dev_t value of 0.
		201	- new treescan option: --grep.
		202	- add more S_IF macros, and major/minor/makedev "macros".
		203
		204	3.71 Thu Dec 30 08:18:46 CET 2010
		205	- the numerical result value passed to callbacks did not stringify
		206	correctly, due to internal reuse and failure to reset the sv flags.
		207	- actually test for posix_[mf]advise, as at least uClibc defines
		208	_POSIX_ADVISORY_INFO without actually having any of the required
		209	funcitonality. ugh.
		210
		211	3.7 Mon Nov 1 23:00:34 CET 2010
		212	- implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
		213	aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
		214	- document the sad state of affairs w.r.t. pthread on many bsds.
		215	- do not enable mmap on systems without _POSIX_MAPPED_FILES
		216	(openbsd 4.8).
		217	- do not leak memory in IO::AIO::mmap when the scalar already
		218	had string-data.
		219	- add O_RDWR, O_APPEND and O_EXCL symbols and semi-document
		220	them.
		221	- cache the result IV, for a minor speedup in the common case.
		222	- croak when an mmapped-scalar changes location, to detect
		223	user-errors better.
		224	- fix aio_readlink prototype.
		225
		226	3.65 Wed Mar 31 02:45:05 CEST 2010
		227	- actually use PATH_MAX instead of NAME_MAX for readlink, as to not
		228	cut off long pathnames in aio_readlink (based on patch by
		229	Rasmus Andersson).
		230	- a double fork partially killed the event pipe (great testcase
		231	by dormando). affects IO::AIO, BDB and Async::Interrupt.
		232	- suck steve's dick and rename our symbols to avoid colliding
		233	with nonstandard identifier spam on the broken os x pseudo-os.
		234	affects IO::AIO and BDB.
		235
		236	3.6 Mon Jan 11 00:43:39 CET 2010
11	- (libeio) more fixes for the freebsd/apple sendfile - broken by	237	- (libeio) more fixes for the freebsd/apple sendfile - broken by
12	manpage standards, but apparently correct accoridng to actual	238	manpage standards, but apparently correct accoridng to actual
