Alas, neither of these signs seems to be happening -- the (internal, IDE)
disk doesn't sound like it's thrashing, and the PythonInterpreter doesn't
jump in memory usage at all -- it's using about 20% of a 23.2 MB memory
allotment.

So...what's your second guess?  ;)

Thanks very much for your reply!  Let me know if I can supply any
additional information that might be useful.

Best,
Phil
