+TODO: aio_cptree/mvtree
+TODO: aio_utime, aio_chmod, aio_chown? should simply stat/open first?

+TODO: fix setsig
+
+2.4
+	- shared code between BDB and IO::AIO.
+        - fix aio_busy w.r.t. fractional delays.
+        - add aio_chmod, aio_chown, aio_utime.
+        - correctly set errno to ENOSYS on unimplemented functions
+          (should never happen, though).
+
+2.33 Tue Jan 23 23:55:41 CET 2007
+	- fix install path (Andreas J. Koenig).
+
+2.32 Mon Jan 22 16:56:23 CET 2007
+	- added aio_rmtree.
+        - wow, aio_mkdir was missing.
+        - aio_load did return undef on error, not -1.
+        - use prefixexp not prefix in autoconf.pm
+          (suggested by ... rt.cpan.org unreachable).
+        - avoid installing autoconf.pm.
+
+2.31 Sat Jan  6 03:46:02 CET 2007
+	- added aio_load.
+
+2.3  Sat Dec 23 05:48:07 CET 2006
+	- fix off-by-one bug in aio_read, causing memory corruption
+          or crashes.
+
+2.21  Fri Dec 22 05:03:38 CET 2006
+	- minor doc updates.
+	- minor cleanups.
+        - IO::AIO::poll returns request count.
+        - undocumented and unfinished async-signal-reporting.
+
+2.2  Tue Oct 31 00:31:00 CET 2006
+	- minor doc updates.
+        - added aio_readlink.
+        - properly zero-terminate aio_read buffer.
+        - fix aio_read/write with nonzero dataoffset.
+        - reduced size of aio request structure.
+        - better diagnostics when pathnames etc. are not byte-encoded;
+          do not leak request in that case, either.
+
+2.1  Sun Oct 29 02:01:57 CET 2006
+        - INCOMPATIBLE CHANGE: replace IO::AIO::poll_some by
+          IO::AIO::max_poll_reqs and IO::AIO::max_poll_time.
+	- fix a bug in aio_move where it would fail everytime
+          it would have to copy files manually.
+	- doc updates.
+	- start threads only on (very low) demand.
+        - end superfluous threads automatically after 10s idling.
+        - add IO::AIO::max_idle to control this.
+	- some tuning applied to random places.
+        - add aio_mknod.
+
+2.0  Thu Oct 26 18:27:58 CEST 2006
+	- minor incompatibility: max_outstanding semantics have changed.
+	- major rewrite, consider all functionality EXPERIMENTAL.
         - aio requests can be cancelled.
-        - add aio_group: aio requests can be grouped.
-        - implement generator interface for groups.
-        - add aio_sleep mainly for benchmarking and debugging.
+        - callbacks can be (re-)set later.
+        - aio requests can choose between 9 priorities.
+        - add aio_group: aio requests can be grouped
+          into composite requests.
+        - generator interface for groups.
+        - add IO::AIO::poll_some.
         - major documentation improvements.
         - very minor bugfixes.
+        - add aio_nop for dummy requests.
+        - add aio_busy mainly for benchmarking and debugging.
+        - use "fast" mutexes on linux.
+        - use dynamic (and larger) buffers instead of
+          putting them onto the stack.
+        - optimise x86 and amd64 a bit.
+        - better error checking when ENOMEM.
+        - hopefully fix mem and dirp leaks on fork.
+        - warn about broken perl malloc.
+        - compiles on cygwin (but pread is broken on cygwin
+          which is not detected by autoconf, so you have to
+          edit autoconf/config.h yourself to enable emulation).
