Look at thread_entryPoint in core.thread for a clue on how TLS is implemented.
Interesting. Now that I've given it more thought, though, using this is probably a bad idea for lightweight task-based concurrency because resetting TLS at all properly would require re-running thread-local module c'tors (arbitrarily expensive), not just blitting a few things (cheap). I guess I'll have to resort to disallowing arbitrary indirection in return types in any safe subset of std.parallelism.
