System clocks are not generally guaranteed to be accurate to the same 
level that processor ticks guarantee. So you can run into cases where 
short sleeps never happen or run arbitrarily too long.

Of course in Ruby (MRI) thread scheduling is largely cooperative, so the 
OP is probably expecting a lot out of it anyway.
