Thanks for the guidance.  It may work for my pirposes, as I dont
intend to use any boost facilities except some basic block allocations
of memory.

One suggestion;  make a 32-vs-64 bit test part of the setup code,
so when a known incompatible producer/consumer relationship exists,
it can gracefully throw an error instead of failing mysteriously.
