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

Ok, I got select.select to work -- this cuts the CPU usage back down to
normal, but now I'm losing KeyboardInterrupt exceptions. Before, I could
ctrl-c my app and it would die. Now they seem to hang the process, and get
queued up in the input buffer somehow.
My change thus far:
pkt, who = PingScheme.icmpSocket.recvfrom(512)
...
Becomes:
readyToRead = select.select([PingScheme.icmpSocket], [], [],
MAX_LOOP_PERIOD)[0]
if readyToRead:
pkt, who = PingScheme.icmpSocket.recvfrom(512)
...
Any guesses what is happening to the ctrl-c's?
