In my application I have a signal that each thread sends at least once a second. If the main thread 
sees no signal for 10 seconds it assumes the child has crashed and notifies the user. None of my 
threads run longer than 10 seconds anyway, but updating progress bars and captions when it was all 
in one thread was enough to throw out sensitive serial timing.

 From my perspective it's nice to be able to notify the user that the compiler has crashed and they 
should save their work before restarting the application.
