-------------------
4.31  Tue Jun  3 03:29:27 CEST 2014
        - work around more 5.20 bugs. backwards compatibility my ass.

4.3   Fri Apr 11 06:22:38 CEST 2014
        - perl5porters broke Async::Interrupt, BDB, EV, IO::AIO, OpenCL
          without warning by switching the meaning of USE_SOCKETS_AS_HANDLES
          in 5.18. What's so attractive about giving a shit about backwards
          compatibility - I will never understand.

4.2   Sat Jan 25 01:13:14 CET 2014
        - aio_group could corrupt memory because it didn't restore
          the stack after req_submit.
        - be more careful on (e.g. permission) errors in bin/treescan.
        - work around changes in ExtUtils::MakeMaker.
        - (libeio) implement aio_realpath for win32.
        - (xthread) work around compile time bugs in ptw32.
        - added IO::AIO::pipesize.
        - (libecb) insignificant update.

4.19  Sun Jan  6 12:47:26 CET 2013
        - avoid endless loop in fiemap with some XFS files.
        - in aio_rename and aio_rmdir, specialcase the case of [$wd, "."]
          and call rename/rmdir instead of renameat/unlinkat.
