That's just a specification. Just match it, and ensure the code
behaves like your customers need.

Yes. Like I said, for windows, a modal window is nothing but a
modeless window with these enhancements:

 - parent window is disabled
 - DoModal calls an event loop for you

That breaks an important GUI guideline that an app should only have
one event loop. MS had to make their windows jump through hoops
(called TranslateMessage()) just to enable custom event loops.

If you TFUI, you should control your event loop, so you will be better
off with a modeless window and the parent window disabled. That will
behave exactly like a modal window.

To do that, all you must do is replace your sleep with a semaphore.
Google will help with that. But now your other thread must send it. So
you are back to using multiple threads to create a single-threaded
program.

A modeless dialog will lead to a better architecture, both test-side
and code-side.
