Indeed, and true for all pre2.6 Pythons.  All the 2.x -> 3.1 guides
effectively assume 2.6 as a floor.  I have the luxury of treating 2.6 as
a floor and tend to forget sometimes the hassles of using anything that
doesn't have the multiprocessing package as standard (*).

Sorry for slipping in a googly (**).

(*) Insert long spiel about multicore, processor bound computing, use of
Python, the GIL, process-orientation, and CSP.

(**) Cricket metaphor nothing to do with anything else that might have
come to mind.
