Right!  Condition variables can also be used on their own.  I've used them
in that way before.  The example given by Jeremy was using CV's as a
monitor, not as CV's in their own right.  I'd recommend leaving pthread CV's
largely as-is, but adding a Monitor class that wraps the while Predicate
loop.

The only problem with the classic Monitor is that it only supports one CV.
So maybe we could just add a function to CV's that take a Predicate & Mutex,
and act out that part of a Monitor -- that way, more advanced users can
quickly define MultiMonitors (Monitors that have multiple CV's).
