When I need to do a "do-this-a-bit-later" kind of call, I always try
gobject.idle_add(func) first. With idle_add() the delay is only as long
as it takes for the requests in the event queue to be processed
(depending on a few things). No more and no less. It's usually less than
any custom time-out value and not specific to the development machine.
IMHO using idle_add() is already an ugly hack. Using timeout_add() (for
things where specific time measurement is not involved) is even uglier
and should be used with caution.
