 =head2 I/O WATCHERS
 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<fh> is the Perl I<file handle> (I<not> file descriptor) to watch
-(AnyEvent might or might not keep a reference to this file handle). C<poll>
+for events (AnyEvent might or might not keep a reference to this file
+handle). Note that only file handles pointing to things for which
+non-blocking operation makes sense are allowed. This includes sockets,
+most character devices, pipes, fifos and so on, but not for example files
+or block devices.
-must be a string that is either C<r> or C<w>, which creates a watcher
+C<poll> must be a string that is either C<r> or C<w>, which creates a
-waiting for "r"eadable or "w"ritable events, respectively. C<cb> is the
+watcher waiting for "r"eadable or "w"ritable events, respectively.
-callback to invoke each time the file handle becomes ready.
+C<cb> is the callback to invoke each time the file handle becomes ready.
 Although the callback might get passed parameters, their value and
 presence is undefined and you cannot rely on them. Portable AnyEvent
 callbacks cannot use arguments passed to I/O watcher callbacks.
