I take that back.  There's a fundamental error in this analysis.  Concurrent
Haskell allows you to get the ThreadId of the current thread, and ThreadId
DOES implement Ord.  I thought of this last night and tried to work out a
way of making the thread with the least ThreadId win, but couldn't quite do
it.  But it may still be possible.
