I'm having a very hard time explaining why this snippet *sometimes*
raises KeyError:
snippet:
print type(self.pool)
for frag in self.pool.keys():
if frag is fragment_info:
print "the fragment_info *is* in the pool", hash(frag),
hash(fragment_info), hash(frag) == hash(fragment_info)
Has anyone tried installing Python on Compute Node Linux (on a cray)? I was
having trouble getting it running. I see that CNL does not support dynamic
libraries but I am not sure what the best way then is to get Python
running.
Any tips?

Hi,
in a module of mine (ftpserver.py) I'd want to add a (boolean) global

because of the "ethical" doubts I'm gonna write below.

Guys thanks to point it out.
Yes, it's a race problem. I tried sleep long enough, then I can
connect to the socket. I should add code to try to connect to the
socket for a given time out.
