12TODO: MS_xxx, posix_fadvise, posix_madvise 22 - (libeio) implement aio_realpath for win32.
13TODO: realpath 23 - (xthread) work around compile time bugs in ptw32.

254.19 Sun Jan 6 12:47:26 CET 2013
26 - avoid endless loop in fiemap with some XFS files.
27 - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
28 and call rename/rmdir instead of renameat/unlinkat.
29
304.18 Thu Oct 11 07:01:26 CEST 2012
31 - fix unintended xthread_create by intentionalising it :)
32
334.17 Thu Oct 11 05:19:47 CEST 2012
34 - rename aio_fallocate to aio_allocate, to match documentation.
35 - add list of linux fsid values to aio_statvfs docs.
36 - work around a bug in btrfs' FIEMAP ioctl implementation.
37 - work around AIX bug: statvfs.f_fsid is a struct, not unsigned long
38 as per unix spec.
39
404.16 Tue Aug 14 05:39:03 CEST 2012
41 - aio_statvfs was wromgly marked for wd emulation, causing
42 it to malfunction for paths.
43 - fix a crash in aio_fiemap, when used on ranges without any
44 extents.
45 - work around linux kernel bug (at least in 3.2): kernel might
46 trash fiemap input arguments.
47 - work around linux kernel bug (at least in 3.2): kernel does not
48 set FIEMAP_EXTENT_LAST on last segment.
49 - work around linux kernel bug (at least in 3.2): kernel silently
50 truncates segment count if a file.
51 - make fh argument of IO::AIO::mmap optional, also add mmap/munmap
52 to quick overview.
53 - splice can corrupt data.
54 - (libeio) remove pread/pwrite emulation.
55 - do not grow mmaped scalars in aio_read.
56 - add FALLOC_FL_PUNCH_HOLE and document fallocate.
57 - provide pread/pwrite for win32, making it link again on native win32.
58
594.15 Tue Apr 10 06:59:00 CEST 2012
60 - always include linux/types.h for fiemap, for compatibility to
61 ancient systems (Paul Howarth).
62 - experimental support for IO::AIO::splice and ::tee (no aio_...).
63 - provide SEEK_HOLE and SEEK_DATA, if available.
64 - work around (again!) an immensely stupid bug in RHEL, defining
65 autoconf macros in linux system headers (analysed by Paul Howarth).
66
674.14 Sat Apr 7 02:45:18 CEST 2012
68 - fix stat structure usage on windows, which caused bogus stat results.
69 - (libeio) make readahead emulation behave more like actual readahead by never failing.
70 - new request aio_seek.
71 - new request aio_fiemap.
72 - autogenerate the #ifdef/#define 0 blocks for symbols we export.
73
744.12 Fri Dec 30 08:51:25 CET 2011
75 - realpath would return a random value if the name was too long,
76 instead of -1.
77 - port to c89.
78
794.11 Mon Oct 10 00:24:11 CEST 2011
80 - libeio didn't compile on !linux (Paul Howarth).
81
824.1 Sun Oct 9 10:24:11 CEST 2011
83 - IO::AIO did access uninitialised memory on unsuccessful stats.
84 - (libeio) added syncfs syscall wrapper.
85 - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
86 - (libeio) support multiple indepenent working directories.
87 - applied speling corrections by Nicholas Bamber.
88 - tune treescan #threads and #outstanding requests a bit.
89 - reduce the number of file descriptors in use at any one time
90 in treescan, to avoid running out of them (and using too much ram).
91 - take advantage of working directoriy abstractions
92 in aio_scandir and treescan.
93 - reduce compiled size by ~10% by not inlining some key functionality.
94 - added --progress switch to treescan.
95
964.0 Mon Jul 18 05:01:10 CEST 2011
97 - INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
98 see FORK BEHAVIOUR in manpage for details.
99 - passes testsuite on win32 now and may actually work
100 (activestate 5.10.1 / MSVC6, YMMV).
101 - (libeio) fix a deadlock where a wakeup signal could be missed when
102 a timeout occured at the same time.
103 - (libeio) added realpath.
104 - (libeio) added fallocate.
105 - (libeio) disabling sendfile on darwin unfortunately broke the emulation.
106 - (libeio) do not acquire any locks when forking.
107 - (libeio) use fewer time() syscalls when waiting for new requests.
