There was one more thing I had originally suggested as an optional
thing to test for:

  is at most clock_getres() nanoseconds behind
  CLOCK_REALTIME/CLOCK_MONOTONIC, and never ahead of it.

It's probably too much to put into this test, and I'm not sure we really
need to test for it. Are you still looking into this, or do you think we should
stop here?
