I've seen these messages too on AIX 5.2.
It seems to come from doing an "import" on piped/fork processes with a
python parent. (In particular import errno)
I don't know the "proper" solution but I got rid of the messages
(similar messages came up when I ran my app) by
hacking Python/thread_pthread.h. There's a CHECK_STATUS macro the does
a perror if any of the sem_* functions don't return
an acceptable status.
I just commented out the perror (didn't seem to hurt the python tests or
my app) but I hope that someone more knowledgeable about
Python internals might tell me if a more serious problem is looming.
