Can you work out why? I guess 1-999650001525879 is a really tiny amount, so perhaps it's OK. However, I'd like to keep the test strict if possible; maybe rather than:

According to the comment in the code the test is meant to be approximate. So we should accept some milliseconds less.
This test is deliberately very strict about the minimum time taken during sleep, and slightly sloppy about over-sleeping. That's because sleep should never wait too little time, but we allow a little extra time due to e.g. the test system being a bit busy and not noticing when the sleep wakes up.
