Have you ever used threads before?

The standard way to handle this problem is to run your gui in one thread
(the main thread) and then spawn a separate thread to handle any real
work that needs doing.


is one way to handle it, but if you've never used threads before, I
suspect it will be hard to understand.  I'm going to be busy for
several hours -- maybe somebody else here can explain.
