Thanks for the reply.
If I understand your meaning, I should do something like this (given I
wish to run an app against several arguments [my use case]):
for lstArgs in pileOflstArgs:
uniqueProcessID = subprocess.Popen([app] + lstArgs)
pid = uniqueProcessID.pid
retcode = uniqueProcessID.poll()
# increment uniqueProcessID
If so, how do I handle the poll() on long-running processes? Run a
bunch and then start a check loop? Am I asking too many questions?
