		50	- changed default for aio_msync flags to MSYNC_SYNC.
		51	- document offset/length behaviour of mprotect/madvise.
		52
		53	4.34 Sun May 1 19:18:24 CEST 2016

		55	compile errors on various platforms.
		56	- major/minor were accidentally switched (reported by Alexander Lishenyuk).
		57	- removed duplicate definition of MAP_HUGETLB, that was found due to
		58	a bug in Perl::Tidy (testcase by alaska332@gmail.com).
		59	- added (untested!) aio_fcntl, aio_ioctl requests.
		60	- (libeio) names set via prctl are truncated to 15 chars + nul, not 16,

		65	- added support for FALLOC_FL_COLLAPSE_RANGE and FALLOC_FL_ZERO_RANGE
		66	constants.
		67	- added support for O_TMPFILE and O_PATH constants.
		68	- added support for MAP_FIXED, MAP_GROWSDOWN,MAP_32BIT, MAP_HUGETLB, MAP_STACK
		69	consdtants, whether they can be sensibly used or not.

		84	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		85	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		86	in 5.18. What's so attractive about giving a shit about backwards
		87	compatibility - I will never understand.
		88
		89	4.2 Sat Jan 25 01:13:14 CET 2014
		90	- aio_group could corrupt memory because it didn't restore

		103
		104	4.18 Thu Oct 11 07:01:26 CEST 2012

		110	- work around a bug in btrfs' FIEMAP ioctl implementation.

		112	as per unix spec.
		113
		114	4.16 Tue Aug 14 05:39:03 CEST 2012
		115	- aio_statvfs was wromgly marked for wd emulation, causing

		117	- fix a crash in aio_fiemap, when used on ranges without any
		118	extents.
		119	- work around linux kernel bug (at least in 3.2): kernel might
		120	trash fiemap input arguments.

		122	set FIEMAP_EXTENT_LAST on last segment.
		123	- work around linux kernel bug (at least in 3.2): kernel silently
		124	truncates segment count if a file.
		125	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		126	to quick overview.
		127	- splice can corrupt data.
		128	- (libeio) remove pread/pwrite emulation.
		129	- do not grow mmaped scalars in aio_read.
		130	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		131	- provide pread/pwrite for win32, making it link again on native win32.
		132
		133	4.15 Tue Apr 10 06:59:00 CEST 2012
		134	- always include linux/types.h for fiemap, for compatibility to
		135	ancient systems (Paul Howarth).
		136	- experimental support for IO::AIO::splice and ::tee (no aio_...).
		137	- provide SEEK_HOLE and SEEK_DATA, if available.
		138	- work around (again!) an immensely stupid bug in RHEL, defining
		139	autoconf macros in linux system headers (analysed by Paul Howarth).
		140
		141	4.14 Sat Apr 7 02:45:18 CEST 2012
		142	- fix stat structure usage on windows, which caused bogus stat results.
		143	- (libeio) make readahead emulation behave more like actual readahead by never failing.
		144	- new request aio_seek.
		145	- new request aio_fiemap.
		146	- autogenerate the #ifdef/#define 0 blocks for symbols we export.
		147
		148	4.12 Fri Dec 30 08:51:25 CET 2011
		149	- realpath would return a random value if the name was too long,
		150	instead of -1.
		151	- port to c89.
		152
		153	4.11 Mon Oct 10 00:24:11 CEST 2011
		154	- libeio didn't compile on !linux (Paul Howarth).
		155
		156	4.1 Sun Oct 9 10:24:11 CEST 2011
		157	- IO::AIO did access uninitialised memory on unsuccessful stats.
		158	- (libeio) added syncfs syscall wrapper.
		159	- (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
		160	- (libeio) support multiple indepenent working directories.
		161	- applied speling corrections by Nicholas Bamber.
		162	- tune treescan #threads and #outstanding requests a bit.
		163	- reduce the number of file descriptors in use at any one time
		164	in treescan, to avoid running out of them (and using too much ram).
		165	- take advantage of working directoriy abstractions
		166	in aio_scandir and treescan.
		167	- reduce compiled size by ~10% by not inlining some key functionality.
		168	- added --progress switch to treescan.
		169
		170	4.0 Mon Jul 18 05:01:10 CEST 2011
		171	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		172	see FORK BEHAVIOUR in manpage for details.
		173	- passes testsuite on win32 now and may actually work
		174	(activestate 5.10.1 / MSVC6, YMMV).

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

		200	- document the fact that fork doesn't work anymore when using
		201	this module, on anything !GNU/Linux.
		202	- increase timeout in t/04_fork.t, as too many CPAN-tester setups
		203	run on a 0.1MHz cpu. Or so.
		204
		205	3.9 Fri May 27 02:43:47 CEST 2011

		209	flags.
		210

		213	- support a max_idle value of 0.

		215
		216	3.72 Fri Feb 11 04:25:38 CET 2011
13	- use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock.	217	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
		218	- aio_mknod always used a dev_t value of 0.
		219	- new treescan option: --grep.
		220	- add more S_IF macros, and major/minor/makedev "macros".
14		221
15	3.71 Thu Dec 30 08:18:46 CET 2010	222	3.71 Thu Dec 30 08:18:46 CET 2010
16	- the numerical result value passed to callbacks did not stringify	223	- the numerical result value passed to callbacks did not stringify
17	correctly, due to internal reuse and failure to reset the sv flags.	224	correctly, due to internal reuse and failure to reset the sv flags.
18	- actually test for posix_[mf]advise, as at least uClibc defines	225	- actually test for posix_[mf]advise, as at least uClibc defines
