Changes for version 2.51 - 2007-10-06
- perlio isn't generally threadsafe, so aio_close could not work reliably. aio_close now tries a safe hack that might not be that asynchronous (see the manpage for details).
- discard callback return values as to not grow the stack endlessly when poll_cb handles many requests without returning.
- minor code cleanups.
- IO::AIO - Asynchronous Input/Output
- autoconf in autoconf.pm
