Here is my working example:

Although Marc Lehmann doesn't come out and say so, IO::AIO provides
two features that support its use from POE in a couple different ways.
It exposes a file descriptor, which can be used to notify select-like
loops when AIO operations are complete. For example:
# POE integration
open my $fh, = . IO::AIO::poll_fileno or die $!;
$_[KERNEL]-select_read($fh, aio_event);
Or you can use its callback mechanism with POE::Session's postback()
or callback():
aio_open /etc/passwd, O_RDONLY, 0, $_[SESSION]-postback
(aio_open_event);
Whether you should use IO::AIO is a matter of your application's
requirements. Quite a lot of systems don't require AIO, so they
shouldn't use IO::AIO.
I hope this helps.

According to the documentation that only does buffered I/O. There are
many other file operations that can block, which IO::AIO deals with-
file opening and creation, closing and deletion, link/symlink, stat,
rename, etc. Does POE handle those as well?

why use IO::AIO when there is POE::Wheel::ReadWrite?

To avoid blocking when doing file operations under POE, shouldn't
IO::AIO be used? I haven't seen any mention or examples of two being
used together. If somebody has done this already, can they post an
example here or on the wiki. Thanks.
Also, there was a brief mention [1] on the djabberd mailing list
that
Brad would like to bring Danga::Socket and POE together. Any
thoughts
from this camp?
