It can still run for a long time but it does so with
a mutex locked.  So I consider the context switch
latency problem resolved.  The algorithm could still
be improved by keeping track of things as part of
alloc/dealloc but I didn't want more memory for a 
heap or region control block.

FWIW based upon Bob's data in private email, it looks
like the amount of free space is about 2x too much.
Does this match for anyone else?
