Okay, I looked at the code and you are right. That code is a mess. It basically calls select/pool with a timeout of 0, then actively does select/pool in management for 1s and does this in a loop. That this totally wrong indeed. I think we should be more radical here. Always do a 1s poll/select timeout and do a 0s management sleep/poll. That will also make the code a bit simpler. Arne
