  I'm working with Atom to program an ATtiny25. I am curious
  about how consistent the timings actually are.

  Consider John Van Enk' example of blinking a LED on an


  We see that sometimes `setLED' is executed and sometimes not.
  When `__clock' is incremented, it will be incremented
  sometimes sooner, sometimes later.

  Also, I am a little puzzled by the `__coverage` variable. What
  does it do?

  As for my project/motivation -- I'm just trying to blink a
  little LED on much less robust/rich kit -- the Trippy RGB
  Waves kit from Lady Ada. I am (gratuitously) exploring ways to
  program it with Haskell.
