One option in which we have both reactor and deferred :)
def do_low_level_stuff(deferred)
try:
deferred.callback(self.get_handle())
except SystemDelayException:
reactor.callLater(1, do_low_level_stuff, deferred)
def do_stuff():
deferred = Deferred()
do_low_level_stuff(deferred)
return deferred
Cheers
