Oh yeah. Well, that might be a pain. It's not technically necessary to
make threads work for __thread to work. But you might not have designed
and implemented a whole TLS ABI for a new processor before trying the port.
But, I think Jonathan is dealing with a new OS port for supported processors.
So TLS support will probably be just fine and the single-threaded case
should work out of the box (probably modulo some random nits).

Not surprising. I meant to mention I anticipated some bit-rot.
But it is worthwhile (to me at least) to see it and fix it up.

Amen.
