I can imagine that a bad socket module might have this effect.  With 
verification that a user file could have this effect, I would augment 
the message.

No.  Quitting because a stdlib module cannot be imported (or corrupted) 
is not a bug.  AttributeError is a typical symptom.  A user file called 
random.py is probably more common.
