Revision history for Perl extension Async::Interrupt.

1.02  Tue Sep  1 18:41:09 CEST 2009
	- prototypes for sig2name/sig2num were missing.

1.01  Wed Aug  5 13:50:59 CEST 2009
	- evpipe->wait did immediately return on !windows.

1.0   Thu Jul 30 05:58:55 CEST 2009
        - implement signal_hysteresis.
        - implement scope_block_func.
        - implement sig2name/sig2num convenience functions.

0.6   Sat Jul 18 07:09:33 CEST 2009
	- add autodrain setting.
        - added Async::Interrupt::EventPipe class.
        - fixed a potential race issue by removing the internal
          epipe state.
        - destroying asyncs inside their handler callback could lead
          to segfaults.
        - destroying an interrupt object did not properly remove it
          from the asyncs list (classical case of side-effect-inside-assert).

0.501 Fri Jul 17 16:58:51 CEST 2009
	- do no longer errornously do operations on fd 0 if no pipe
          is associated with the interrupt object.

0.5   Fri Jul 17 03:53:21 CEST 2009
	- INCOMPATIBLE CHANGE: signalling the value 0 is no longer allowed.
	- added automatic pipe creation code, including post_fork method.
        - added ->c_var method, and the ability to use a perl scalar as
          signal checker.

0.042 Tue Jul 14 21:51:04 CEST 2009
	- enforce initialisation of perl's signal handling framework,
          avoiding crashes otherwise.
	- switched to common::sense.
        - freely sprinkle around more volatiles.
        - fix initialisation code (XSLoader).
        - ported to win32.

        - oh my, I forgot to include the typemap.
	- improved documentation.

0.04  Sun Jul 12 00:24:02 CEST 2009
	- added ability to block the pipe write temporarily.
        - added the ability to call signal when the process receives
          a (POSIX) signal.
	- removed debugging output in constructor.
        - support eventfd instead of a pipe (untested).

0.03  Fri Jul  3 23:11:05 CEST 2009
