To a first approximation, you should never use multiple threads in a PyGTK
application.  There is almost always an easier solution.

It is possible to write stable, correct multithreaded software with PyGTK,
but it is not easy, and there are very few people who know how to do it
reliably.  PyGTK is designed principally for single-threaded use.

I believe that you do have to call threads_init() yourself.  As I remember
it, Sugar does not make this call for you.
