It's a piece of crap, but you're welcome to try to fix it up. See attached.
With respect to the apparent lack of impact of the sleep loop, I can
only speculate that this test case doesn't really mimic real-world
conditions inside the backend very well. There is a lot more going on
there - multiple locks, lots of memory access, etc. But I don't
really understand it either.
