Take a look at the documentation for the threading module here:
http://docs.python.org/release/2.6/library/threading.html, and the
discussion on daemon vs non-daemon threads here:
http://blog.doughellmann.com/2008/01/pymotw-threading_13.html

Basically, as long as at least one non-daemon thread is still running,
your program will not exit.
