This piece of code prohibits cooperative scheduling in 599 999 999 out of
600 000 000 times. It's a nice example how to not code in Go. Particularly,
delays should be implemented using the functions in the time package, not
by burning CPU cycles at the expense of other useful work that could have
been done instead.
