There are pieces with different licenses but they only differ in the
names of the beneficiaries, not in the conditions (although the words
aren't always exactly the same).  As far as I can tell, this is the
situation for asyncore.py and asynchat.py: they have a copyright
notice of their own (see the 1.5.2 source for the exact text) with Sam 
Rushing's copyright.

As far as I know, yes.  Sam Rushing promised me this when he gave them 
to me for inclusion.  (I've had a complaint that they aren't the
latest -- can someone confirm this?)
