... and if it happens (usually to accomplish operations which take much
time to execute and would freeze the GUI), it is much easier to keep the
worker thread separate from the gtk functions (by using a buffer -
usually, just a list, a dictionary or even a simple int - that the
worker thread populates and the main thread just periodically looks at).

... and if you _really_ need a (non main) thread to play with gtk, don't
forget to use threads_enter and thread_leave
