COPYING: Everything I've done is CC0

I imagine the examples I copied from the Python docs are under the
PSF-2, since that's the most recent license listed in Python 3.3.0's
LICENSE file.  That said, I think the chunks copied are short enough
to qualify as fair use.

grab-cores.py: Use threading.Thread to call spam.busy

Usually Python threads can only use one core at a time due to the
Python global interpreter lock.  This script allows us to see if
dropping the GIL with Py_BEGIN_ALLOW_THREADS allows us to use multiple
cores simultaneously.

Increasing the number of threads time sharing on the same core does
not increase total execution time if the threads are only checking for
elapsed time.  We need them to actually *do* something.
