Not sure yet. My next goal is no-alloc promise-future, also based on 
spinlocks.

I don't intend to "finish" concurrent_unordered_map past what is 
already done, and I suspect no Boost library will accept it until I 
or someone else does.

I do intend to develop a partial C++ 11 STL to Boost shim library, so 
one no longer needs the rest of Boost to use Boost.Thread standalone 
for example. That way we can push Boost.Thread ahead without needing 
Boost.

I originally started expecting to make great use of Intel TSX. Read 
this list's archives for how badly that fared.
