// and install our own event handler loop... But this can only
// be done when the globalMutex is unlocked first and locked
// after...

One thing I have noticed is that applications sometimes don't exit
correctly. Their icon remains in the taskbar and they tend to
relaunch themselves automatically. I believe this problem doesn't
occur if you exit your application using the exit() method. However,
if you end main() with 'return 0;' or so, this seems to happen.
