Then we might need to emulate thread-local storage somehow. This can be a
bit tricky, since __thread/__declspec(thread) are not types, but
storage-class modifiers. My first thought was to provide a small class with
a syncronized map[thread_id] -> value container as fall-back emulation, but
that will not be possible unless we "templatize" the
BOOST_THREAD_LOCAL_RESTRICTED by type somehow. Any thoughts on this?

Sounds great!
