Of course, but 30 seconds look a little bit too much to me, also
because (I might be wrong here) I noticed that a smaller timeout seems
to result in better performances.
Plus, if scheduled callbacks are ever gonna be added to asyncore we
would be forced to lower the default timeout anyway in order to have a
decent reactivity.
