Though I love the idea to use Cygwin for everything, including stuff
like simulating the universe bit-accurate in realtime, it might be a
teeny bit daring to expect microsecond precision in an emulation layer.
You should contemplate the idea to use native Windows functions if
you need such precision.

Jason is right, btw., see
