[Idle-dev] re: Leaving subprocesses hanging

[John Zelle]

I did some more checking on this. My fix _does_ seem to work on IDLE 
1.1. I'm not sure what I was doing wrong before. It may be that I was 
accidently mixing my 2.3 and 2.4 libraries. Or maybe I'm  just suffering 
from too much end-of-term grading :-).
