		41	TODO: aio_fcntl/ioctl test.
		42
		43	- add MADV_FREE constant.
		44
		45	4.34 Sun May 1 19:18:24 CEST 2016
		46	- def0.h was not properly generated during previous release, causing
		47	compile errors on various platforms.
		48	- major/minor were accidentally switched (reported by Alexander Lishenyuk).
		49	- removed duplicate definition of MAP_HUGETLB, that was found due to
		50	a bug in Perl::Tidy (testcase by alaska332@gmail.com).
		51	- added (untested!) aio_fcntl, aio_ioctl requests.
		52	- (libeio) names set via prctl are truncated to 15 chars + nul, not 16,
		53	as manpages-dev originally claimed.
		54
		55	4.33 Mon Jan 18 12:50:10 CET 2016
		56	- add IO::AIO::pipe2 function.
		57	- added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
		58	constants.
		59	- added support for O_TMPFILE and O_PATH constants.
		60	- added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
		61	consdtants, whether they can be sensibly used or not.
		62	- use NO_INIT where applicable.
		63	- update libecb.

		66
		67	4.32 Wed Feb 11 20:32:11 CET 2015
		68	- replace off_t by STRLEN where appropriate, should not result in

		74
		75	4.3 Fri Apr 11 06:22:38 CEST 2014
		76	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		77	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		78	in 5.18. What's so attractive about giving a shit about backwards
		79	compatibility - I will never understand.
		80
		81	4.2 Sat Jan 25 01:13:14 CET 2014
		82	- aio_group could corrupt memory because it didn't restore
		83	the stack after req_submit.

		92	- avoid endless loop in fiemap with some XFS files.
		93	- in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
		94	and call rename/rmdir instead of renameat/unlinkat.
		95
		96	4.18 Thu Oct 11 07:01:26 CEST 2012
		97	- fix unintended xthread_create by intentionalising it :)
		98
		99	4.17 Thu Oct 11 05:19:47 CEST 2012

		104	as per unix spec.
		105
		106	4.16 Tue Aug 14 05:39:03 CEST 2012
		107	- aio_statvfs was wromgly marked for wd emulation, causing

		109	- fix a crash in aio_fiemap, when used on ranges without any
		110	extents.
		111	- work around linux kernel bug (at least in 3.2): kernel might
		112	trash fiemap input arguments.
		113	- work around linux kernel bug (at least in 3.2): kernel does not
		114	set FIEMAP_EXTENT_LAST on last segment.
		115	- work around linux kernel bug (at least in 3.2): kernel silently
		116	truncates segment count if a file.
		117	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		118	to quick overview.
		119	- splice can corrupt data.
		120	- (libeio) remove pread/pwrite emulation.
		121	- do not grow mmaped scalars in aio_read.
		122	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		123	- provide pread/pwrite for win32, making it link again on native win32.
		124
		125	4.15 Tue Apr 10 06:59:00 CEST 2012
		126	- always include linux/types.h for fiemap, for compatibility to
		127	ancient systems (Paul Howarth).
		128	- experimental support for IO::AIO::splice and ::tee (no aio_...).
		129	- provide SEEK_HOLE and SEEK_DATA, if available.
		130	- work around (again!) an immensely stupid bug in RHEL, defining
		131	autoconf macros in linux system headers (analysed by Paul Howarth).
		132
		133	4.14 Sat Apr 7 02:45:18 CEST 2012
		134	- fix stat structure usage on windows, which caused bogus stat results.
		135	- (libeio) make readahead emulation behave more like actual readahead by never failing.
		136	- new request aio_seek.
		137	- new request aio_fiemap.
		138	- autogenerate the #ifdef/#define 0 blocks for symbols we export.
		139
		140	4.12 Fri Dec 30 08:51:25 CET 2011
		141	- realpath would return a random value if the name was too long,
		142	instead of -1.
		143	- port to c89.
		144
		145	4.11 Mon Oct 10 00:24:11 CEST 2011
		146	- libeio didn't compile on !linux (Paul Howarth).
		147
		148	4.1 Sun Oct 9 10:24:11 CEST 2011
		149	- IO::AIO did access uninitialised memory on unsuccessful stats.
		150	- (libeio) added syncfs syscall wrapper.
		151	- (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
		152	- (libeio) support multiple indepenent working directories.
		153	- applied speling corrections by Nicholas Bamber.
		154	- tune treescan #threads and #outstanding requests a bit.
		155	- reduce the number of file descriptors in use at any one time
		156	in treescan, to avoid running out of them (and using too much ram).
		157	- take advantage of working directoriy abstractions
		158	in aio_scandir and treescan.
		159	- reduce compiled size by ~10% by not inlining some key functionality.
		160	- added --progress switch to treescan.
		161
		162	4.0 Mon Jul 18 05:01:10 CEST 2011
		163	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		164	see FORK BEHAVIOUR in manpage for details.
		165	- passes testsuite on win32 now and may actually work
		166	(activestate 5.10.1 / MSVC6, YMMV).

		168	a timeout occured at the same time.
		169	- (libeio) added realpath.
		170	- (libeio) added fallocate.
		171	- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
		172	- (libeio) do not acquire any locks when forking.
		173	- (libeio) use fewer time() syscalls when waiting for new requests.
		174
		175	3.93 Wed Jun 29 23:44:18 CEST 2011
		176	- ECB.H WAS MISSING.
		177
		178	3.92 Wed Jun 29 14:45:41 CEST 2011
		179	- ecb.h was missing.
		180
		181	3.91 Wed Jun 29 13:24:42 CEST 2011
		182	- (libeio) work around a Linux (and likely FreeBSD and other
		183	kernels) bug where sendfile would not transfer all the requested
		184	bytes on large transfers, using a heuristic.
		185	- buggy sendfile caused aio_move/copy to sometimes fail for big
		186	files (fortunately it checks that the whole file has been
		187	transferred...)
		188	- use libecb for higher performance and higher portability.
		189	- (libeio) disable sendfile on darwin, it's too broken.
		190	- disable fork tests on !linux, as only linux supports mixing

		192	- document the fact that fork doesn't work anymore when using
		193	this module, on anything !GNU/Linux.
		194	- increase timeout in t/04_fork.t, as too many CPAN-tester setups
		195	run on a 0.1MHz cpu. Or so.
		196
		197	3.9 Fri May 27 02:43:47 CEST 2011
		198	- (libeio) fix memory corruption in aio_readdirx for the flags
		199	combination READDIR_STAT_ORDER \| READDIR_DIRS_FIRST.

		201	flags.
		202
		203	3.8 Sun Mar 27 12:25:33 CEST 2011

		205	- support a max_idle value of 0.

		207
		208	3.72 Fri Feb 11 04:25:38 CET 2011
13	- use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock.	209	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
		210	- aio_mknod always used a dev_t value of 0.
14	- new treescan option: --grep.	211	- new treescan option: --grep.
		212	- add more S_IF macros, and major/minor/makedev "macros".

17	- the numerical result value passed to callbacks did not stringify	215	- the numerical result value passed to callbacks did not stringify
18	correctly, due to internal reuse and failure to reset the sv flags.	216	correctly, due to internal reuse and failure to reset the sv flags.
