		47	(see aio_ioctl docs).
		48	- treescan now has a proper manpage and useful --help output.
		49	- new option --sync in treescan, to sync everything in a subtree.
		50
		51	4.34 Sun May 1 19:18:24 CEST 2016

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

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

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

		110	as per unix spec.
		111
		112	4.16 Tue Aug 14 05:39:03 CEST 2012
		113	- aio_statvfs was wromgly marked for wd emulation, causing

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

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

		174	a timeout occured at the same time.
		175	- (libeio) added realpath.

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

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

		207	flags.
		208

		213
		214	3.72 Fri Feb 11 04:25:38 CET 2011
13	- use _POSIX_MEMLOCK_RANGE to detetc mlock/munlock.	215	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
		216	- aio_mknod always used a dev_t value of 0.
		217	- new treescan option: --grep.
		218	- add more S_IF macros, and major/minor/makedev "macros".
14		219
15	3.71 Thu Dec 30 08:18:46 CET 2010	220	3.71 Thu Dec 30 08:18:46 CET 2010
16	- the numerical result value passed to callbacks did not stringify	221	- the numerical result value passed to callbacks did not stringify
17	correctly, due to internal reuse and failure to reset the sv flags.	222	correctly, due to internal reuse and failure to reset the sv flags.
