 You can create an I/O watcher by calling the C<< AnyEvent->io >> method
 with the following mandatory key-value pairs as arguments:
 
-C<fh> the Perl I<file handle> (I<not> file descriptor) to watch
-for events. C<poll> must be a string that is either C<r> or C<w>,
-which creates a watcher waiting for "r"eadable or "w"ritable events,
-respectively. C<cb> is the callback to invoke each time the file handle
-becomes ready.
