23	O_DIRECT	25	4.31 Tue Jun 3 03:29:27 CEST 2014
24	O_LARGEFILE	26	- work around more 5.20 bugs. backwards compatibility my ass.
25	O_NOATIME

27	TODO: document/test madvise
28		27
		28	4.3 Fri Apr 11 06:22:38 CEST 2014
		29	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		30	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		31	in 5.18. What's so attractive about giving a shit about backwards
		32	compatibility - I will never understand.
		33
		34	4.2 Sat Jan 25 01:13:14 CET 2014
		35	- aio_group could corrupt memory because it didn't restore
		36	the stack after req_submit.
		37	- be more careful on (e.g. permission) errors in bin/treescan.
		38	- work around changes in ExtUtils::MakeMaker.
		39	- (libeio) implement aio_realpath for win32.
		40	- (xthread) work around compile time bugs in ptw32.
		41	- added IO::AIO::pipesize.
		42	- (libecb) insignificant update.
		43
		44	4.19 Sun Jan 6 12:47:26 CET 2013
		45	- avoid endless loop in fiemap with some XFS files.
		46	- in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
		47	and call rename/rmdir instead of renameat/unlinkat.
		48
		49	4.18 Thu Oct 11 07:01:26 CEST 2012
		50	- fix unintended xthread_create by intentionalising it :)
		51
		52	4.17 Thu Oct 11 05:19:47 CEST 2012
		53	- rename aio_fallocate to aio_allocate, to match documentation.
		54	- add list of linux fsid values to aio_statvfs docs.
		55	- work around a bug in btrfs' FIEMAP ioctl implementation.
		56	- work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
		57	as per unix spec.
		58
		59	4.16 Tue Aug 14 05:39:03 CEST 2012
		60	- aio_statvfs was wromgly marked for wd emulation, causing
		61	it to malfunction for paths.
		62	- fix a crash in aio_fiemap, when used on ranges without any
		63	extents.
		64	- work around linux kernel bug (at least in 3.2): kernel might
		65	trash fiemap input arguments.
		66	- work around linux kernel bug (at least in 3.2): kernel does not
		67	set FIEMAP_EXTENT_LAST on last segment.
		68	- work around linux kernel bug (at least in 3.2): kernel silently
		69	truncates segment count if a file.
		70	- make fh argument of IO::AIO::mmap optional, also add mmap/munmap
		71	to quick overview.
		72	- splice can corrupt data.
		73	- (libeio) remove pread/pwrite emulation.
		74	- do not grow mmaped scalars in aio_read.
		75	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		76	- provide pread/pwrite for win32, making it link again on native win32.
		77
		78	4.15 Tue Apr 10 06:59:00 CEST 2012
		79	- always include linux/types.h for fiemap, for compatibility to
		80	ancient systems (Paul Howarth).
		81	- experimental support for IO::AIO::splice and ::tee (no aio_...).
		82	- provide SEEK_HOLE and SEEK_DATA, if available.
		83	- work around (again!) an immensely stupid bug in RHEL, defining
		84	autoconf macros in linux system headers (analysed by Paul Howarth).
		85
		86	4.14 Sat Apr 7 02:45:18 CEST 2012
		87	- fix stat structure usage on windows, which caused bogus stat results.
		88	- (libeio) make readahead emulation behave more like actual readahead by never failing.
		89	- new request aio_seek.
		90	- new request aio_fiemap.
		91	- autogenerate the #ifdef/#define 0 blocks for symbols we export.
		92
		93	4.12 Fri Dec 30 08:51:25 CET 2011
		94	- realpath would return a random value if the name was too long,
		95	instead of -1.
		96	- port to c89.
		97
		98	4.11 Mon Oct 10 00:24:11 CEST 2011
		99	- libeio didn't compile on !linux (Paul Howarth).
		100
		101	4.1 Sun Oct 9 10:24:11 CEST 2011
		102	- IO::AIO did access uninitialised memory on unsuccessful stats.
		103	- (libeio) added syncfs syscall wrapper.
		104	- (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
		105	- (libeio) support multiple indepenent working directories.
		106	- applied speling corrections by Nicholas Bamber.
		107	- tune treescan #threads and #outstanding requests a bit.
		108	- reduce the number of file descriptors in use at any one time
		109	in treescan, to avoid running out of them (and using too much ram).
		110	- take advantage of working directoriy abstractions
		111	in aio_scandir and treescan.
		112	- reduce compiled size by ~10% by not inlining some key functionality.
		113	- added --progress switch to treescan.
		114
		115	4.0 Mon Jul 18 05:01:10 CEST 2011
		116	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
		117	see FORK BEHAVIOUR in manpage for details.
		118	- passes testsuite on win32 now and may actually work
		119	(activestate 5.10.1 / MSVC6, YMMV).
		120	- (libeio) fix a deadlock where a wakeup signal could be missed when
		121	a timeout occured at the same time.
		122	- (libeio) added realpath.
		123	- (libeio) added fallocate.
		124	- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
		125	- (libeio) do not acquire any locks when forking.
		126	- (libeio) use fewer time() syscalls when waiting for new requests.
		127
		128	3.93 Wed Jun 29 23:44:18 CEST 2011
		129	- ECB.H WAS MISSING.
		130
		131	3.92 Wed Jun 29 14:45:41 CEST 2011
		132	- ecb.h was missing.
		133
		134	3.91 Wed Jun 29 13:24:42 CEST 2011
		135	- (libeio) work around a Linux (and likely FreeBSD and other
		136	kernels) bug where sendfile would not transfer all the requested
		137	bytes on large transfers, using a heuristic.
		138	- buggy sendfile caused aio_move/copy to sometimes fail for big
		139	files (fortunately it checks that the whole file has been
		140	transferred...)
		141	- use libecb for higher performance and higher portability.
		142	- (libeio) disable sendfile on darwin, it's too broken.
		143	- disable fork tests on !linux, as only linux supports mixing
		144	pthread and fork in perl.
		145	- document the fact that fork doesn't work anymore when using
		146	this module, on anything !GNU/Linux.
		147	- increase timeout in t/04_fork.t, as too many CPAN-tester setups
		148	run on a 0.1MHz cpu. Or so.
		149
		150	3.9 Fri May 27 02:43:47 CEST 2011
		151	- (libeio) fix memory corruption in aio_readdirx for the flags
		152	combination READDIR_STAT_ORDER \| READDIR_DIRS_FIRST.
		153	- add lots of newer POSIX and GNU/Linux-specific open
		154	flags.
		155
		156	3.8 Sun Mar 27 12:25:33 CEST 2011
		157	- use nonstandard but maybe-working-on-bsd fork technique.
		158	- support a max_idle value of 0.
		159	- support setting of idle timeout value (IO::AIO::idle_timeout).
		160
		161	3.72 Fri Feb 11 04:25:38 CET 2011
		162	- use _POSIX_MEMLOCK_RANGE to detect mlock/munlock.
		163	- aio_mknod always used a dev_t value of 0.
		164	- new treescan option: --grep.
		165	- add more S_IF macros, and major/minor/makedev "macros".
		166
		167	3.71 Thu Dec 30 08:18:46 CET 2010
		168	- the numerical result value passed to callbacks did not stringify
		169	correctly, due to internal reuse and failure to reset the sv flags.
		170	- actually test for posix_[mf]advise, as at least uClibc defines
		171	_POSIX_ADVISORY_INFO without actually having any of the required
		172	funcitonality. ugh.
		173
		174	3.7 Mon Nov 1 23:00:34 CET 2010
		175	- implement/add madvise, mmap, munmap, aio_mlockall, munlockall,
		176	aio_mlock, munlock, msync and mtouch to @EXPORT_OK.
		177	- document the sad state of affairs w.r.t. pthread on many bsds.
		178	- do not enable mmap on systems without _POSIX_MAPPED_FILES
		179	(openbsd 4.8).
29	- do not leak memory in IO::AIO::mmap when the scalar already	180	- do not leak memory in IO::AIO::mmap when the scalar already
