=> async request successfully registered

=> async has not been served yet - TIMEOUT.
The reason is that the file descriptot for serial port had not been
polled in the meantime.

OK, I know what to do about that. When register_async is called with a new
request, we must immediately look for pending events, as we do with
sockets.

Thanks for spotting this, expect a patch soon.
