Changes for version 0.6 - 2009-07-18
- 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.
- destoying an interrupt object did not properly remove it from the asyncs list (classical case of side-effect-inside-assert).
- Async::Interrupt - allow C/XS libraries to interrupt perl asynchronously
