It depends on your reason for using threads. Sometimes, it just means
that you can write cleaner code. Having a multiprocessor, and using
multiple threads, and caring about the execution time of the Python
interpreter are putting you in something of a minority.

For one thing, it means that you are using an interpreted language
for something performance critical. In a lot of problems, the inner
loop is likely to end up in external modules which will multiprocess
fine anyway. If yours isn't one of them them sure, go ahead.
