how do I listen on a socket without sucking up all the CPU time?

Quoth blablu at gmx.net (Mike 'Cat' Perkonigg):
| I have some threads which are just looking if a queue is filled. So the 
| main loop of these threads consist of:
|
| while runFlag:
|     	if inQueue.empty() == 0:
|     	    	doSomething...
|
| I could do:
|
| while runFlag:
|     	inData = inQueue.get(1)
|     	doSomething...
|
| but if I do that I can't check runFlag most of the time.
|
| My main understanding problem is now, what I have to do if I want to check 
| this queue every 10 seconds without blocking other threads.
| Can I use time.sleep(10) as a timer or will that block the thread 
| switching?

No, I'm sure time.sleep() will release the interpreter lock.  Try it!
