Again I am not as familiar as I would like to be with the internals of gcc 
or libstdc++, but I understand that the atomic functions employ spin-locks 
for efficiency.  If that is the case then wouldn't they spin perpetually and 
consume 100% CPU if dead-lock were to occur?  This was just an assumption, 
but I will take your advice and step in with the debugger to verify.

Great suggestion.  I will try building it in Linux and take advantage of 
Valgrind.
