sorry i haven't had time to be more responsive. i've got a lot of other work on my hands at the moment, so i'll throw in my best educated guess instead of a thorough analysis, and hope it helps.
First off, i believe that this problem is either system dependent or showing itself through list configs that i don't have. i'm not seeing this under linux or solaris2.5.1, and both installations have taken a bit of a beating.
secondly, this problem probably results from calling os.popen(<prg>, "w") where <prg> does this right off the bat:
if not os.fork(): # do the work os._exit(0)
the way i understand os._exit(0) is that it should only be used for child processes, not parent processes, when a fork() is done. Perhaps there are some underlying things in the system or list configs which cause the parent program to exit before the child is done reading stdin.
at any rate, if those who are experiencing this problem could try replacing the os._exit(0) in the function "main()" in scripts/deliver with "sys.exit(0)" or some such, this *might* fix the problem.
I *think* that should be changed anyway, but could be mistaken.
that's my best educated guess.
if it don't help, i hope to be able to address more of this later this week, but can't promise anything yet.
good luck,
scott
