Exactly!  That is definitely it.  I was sitting in a small
loop doing a time.sleep() every so often, and during the
entire test that thread probably executed only about forty
or fifty bytecodes.

Your technique with the "busy loop" works, as does setting
sys.setcheckinterval() to a much smaller value than the
default 100.

Thanks Thomas!
