Those three words/phrases strike a real discord.

Multithreading is not the same as multiprocessing.  And you probably 
don't ever want to update a window with a different thread than the one 
that created it.  Not that it can't be done, at least in some languages, 
but that it's real rat-hole of problems.

The extra thread or process (with different problems to each) should be 
doing the "logic is running" but NOT the gui.
