Summary: select module doesn't allow any iterable.

Initial Comment:
The select module only allows lists, not any 
iterable.  While this may slightly increase efficiency 
for the select.select() function itself, for many 
applications passing select.select a sets.Set would 
probably be much more efficient (i.e., when things 
are being added/removed from the readable or 
writable lists quite often, the O(n) removal of lists 
would certainly be worse than the O(1) removal of 
sets.)

Using select.poll() instead of select.select() might be a
good alternative, at least on platforms that support it, if
the sets are getting large enough for you to want to avoid
having to build lists explicitely as in :

    select.select(list(a), list(b), list(c))
