The short answer is "because there's a big difference between
'a research project that aims to show feasibility and run some
benchmarks' and 'a portable and robust product-quality implementation
that we could maintain and release'". So far nobody has shown
much interest in working on the latter.
FWIW, I hope to pick up again the work that I talked about at KVM Forum
2013. If completed, this should make multithreaded TCG much simpler
(though not easy by any means). I don't plan to work on multithreaded
TCG myself, though.
