Be happy that your program makes use of both cores? :]

You can restrict your program from using more than one core by setting
the cpu affinity. On Windows the pywin32 packages wraps all necessary calls:

phandle = win32process.GetCurrentProcess()
win32process.SetProcessAffinityMask(phandle, mask)

Past week I've written a wrapper for the Linux syscalls
sched_setaffinity and friends. I may be able and allowed to release the
stuff in a few weeks.
