ThreadDelay is a perfectly reasonable test: it tests that threadDelay 
doesn't wait for *less* time than was requested.  Clearly something is 
wrong on your machine with either threadDelay or the way time is measured, 
but we haven't seen the same symptoms elsewhere so it's hard to diagnose. 
Still, we should try to investigate at some point.
