Okay, I'll eat the donuts. Although I don't need them either.

To me it doesn't specify if the child .exe is allowed to close itself. And it certainly would be easy enough to add a (perhaps hidden) method to do so.

Proper error handling would make sure semaphore is always deleted. Except for C0005 exceptions. And if there are enough of those happening, he's got bigger fish to fry (figure out that problem) than worrying about how the user closed program2.

Have I made you hungry yet with food talk? :)
