We're running into the problem described in bug 1177468, where urandom tries 
to
use a cached file descriptor that was closed by a daemonizing function. A 
quick
fix/workaround is to have os.urandom open /dev/urandom everytime it gets 
called
instead of using the a cached fd.
 Would that create any problems other that those related to the additional 
system
call overhead?
 BTW, I added the traceback we're getting as comment to the bug.
 Thanks
 PS
 This is with Python 2.4.1
