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

		106	as per unix spec.
		107
		108	4.16 Tue Aug 14 05:39:03 CEST 2012
		109	- aio_statvfs was wromgly marked for wd emulation, causing

		112	extents.
		113	- work around linux kernel bug (at least in 3.2): kernel might

		116	set FIEMAP_EXTENT_LAST on last segment.
		117	- work around linux kernel bug (at least in 3.2): kernel silently
		118	truncates segment count if a file.

		120	to quick overview.

		123	- do not grow mmaped scalars in aio_read.
		124	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		125	- provide pread/pwrite for win32, making it link again on native win32.
		126
		127	4.15 Tue Apr 10 06:59:00 CEST 2012
		128	- always include linux/types.h for fiemap, for compatibility to

		131	- provide SEEK_HOLE and SEEK_DATA, if available.
		132	- work around (again!) an immensely stupid bug in RHEL, defining
		133	autoconf macros in linux system headers (analysed by Paul Howarth).

		155	- applied speling corrections by Nicholas Bamber.
		156	- tune treescan #threads and #outstanding requests a bit.
		157	- reduce the number of file descriptors in use at any one time
		158	in treescan, to avoid running out of them (and using too much ram).
		159	- take advantage of working directoriy abstractions
		160	in aio_scandir and treescan.
		161	- reduce compiled size by ~10% by not inlining some key functionality.
		162	- added --progress switch to treescan.
		163
		164	4.0 Mon Jul 18 05:01:10 CEST 2011
