The wording of the current draft reflects the intention
of the committee that there shall be no data race and
no per-thread local terminate handler, see the proposal

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2010/n3189.htm

which became accepted in Batavia 2010. Per-thread handlers are often
hard to manage and it is always possible to define a single handler
that again queries a thread-local to get the actual handler, if you
really want, but not vice versa.
