Many GUI toolkits are single-threaded.  And in fact with GTK and MFC you
can't (or shouldn't) call GUI calls from a thread other than the main
GUI thread.  That's not to say GUI programs don't use threads and put
the GUI it its own thread.  But GUI toolkits are often *not*
multithreaded.  They are, however, often asynchronous, which is often
more cost-effective than multi-threaded.
