Changes for version 0.9 - 2005-07-20
- allow recursive calls to poll_cb, use less locking calls, too.
- fix the Gtk2-example in the SYNOPSIS.
- use pread/pwrite not pread64/pwrite64. this was simply a leftover from Linux::AIO. (found by compiling on cygwin. Unfortunately, cygwin declares but does not implement pread/pwrite).
- only include <sys/syscall.h> on linux.
- IO::AIO - Asynchronous Input/Output
