		79	- perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
		80	without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
		81	in 5.18. What's so attractive about giving a shit about backwards
		82	compatibility - I will never understand.
		83
		84	4.2 Sat Jan 25 01:13:14 CET 2014

		107	as per unix spec.
		108
		109	4.16 Tue Aug 14 05:39:03 CEST 2012

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

		121	to quick overview.
		122	- splice can corrupt data.
		123	- (libeio) remove pread/pwrite emulation.
		124	- do not grow mmaped scalars in aio_read.
		125	- add FALLOC_FL_PUNCH_HOLE and document fallocate.
		126	- provide pread/pwrite for win32, making it link again on native win32.
		127
		128	4.15 Tue Apr 10 06:59:00 CEST 2012
		129	- always include linux/types.h for fiemap, for compatibility to

		132	- provide SEEK_HOLE and SEEK_DATA, if available.
		133	- work around (again!) an immensely stupid bug in RHEL, defining
		134	autoconf macros in linux system headers (analysed by Paul Howarth).
		135
		136	4.14 Sat Apr 7 02:45:18 CEST 2012

		156	- applied speling corrections by Nicholas Bamber.
		157	- tune treescan #threads and #outstanding requests a bit.

		160	- take advantage of working directoriy abstractions
		161	in aio_scandir and treescan.
		162	- reduce compiled size by ~10% by not inlining some key functionality.

		164
		165	4.0 Mon Jul 18 05:01:10 CEST 2011
