+	- 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.
+
+2.5  Thu Oct  4 14:49:08 CEST 2007
+	- replaced _fd2fh with faster xs code.
+        - aio_close will now try to do "the right thing" and thus might
+          work sensibly for the very first time.
+
+2.41 Mon Sep 24 21:28:21 CEST 2007
+	- after fork, invest some work to make sure that the poll_fileno
+          stays stable (by dup2'ing the new fd over the old one), to make
+          it easier for programs/libs that don't control their forking
+          behaviour and cannot recreate their watchers.

         - add aio_truncate, aio_chmod, aio_chown, aio_utime (linux
           successfully demonstrated that you can block on futimes...).
