Python script produces "sem_trywait: Permission denied"

[Mark E. Hamilton]

Sorry, I probably should have re-stated the problem:

We're using Python 2.3.5 on AIX 5.2, and get the follow error messages 
from some of our code. I haven't yet tracked down exactly where it's 
coming from:

sem_trywait: Permission denied
sem_wait: Permission denied
sem_post: Permission denied

We don't run these scripts as root, so I can't say whether they work as 
root. I suspect they would, though, since root has permissions to do 
anything.
