I've tried measuring it and this is what I've found -

	* the window is bigger on more heavily loaded systems.
	* anyone can heavily load a system.
	* you can fake it using "nice".

Regarding the first point, on a lightly loaded system I had trouble
exploiting the bug.  But when I made the system crawl, I hit the
hole the first or second time around almost every time.
