Attempting to use an interval of time less than 1ms would cause \watch to hang. This was confusing, so let's change the logic so as an interval lower than 1ms behaves the same as 0. Comments are added to mention that the internals of do_watch() had better rely on "sleep_ms", the interval value in milliseconds. While on it, this commit adds a test to check the behavior of interval values less than 1ms. \watch hanging for interval values less than 1ms existed before 6f9ee74d45aa, that has changed the code to support an interval value of 0.
