I discovered a rather nasty side effect of the standard cmd.py library today. If it's sitting inside raw_input(), any SIGCLDs that get sent to your application get silently eaten and ignored. I'm assuming that this is something that readline is thoughtfully doing for me. This patch adds an instance attr that allows the user to select to not use raw_input(), but instead use sys.stdin.readline()
