So far as the swap-reuse issue goes, I don't see that a PF_ flag
would help: the threads that already worry about such issues do
the set_freezable()/try_to_freeze() thing, and won't get into
trouble anyway; we don't want to force every other thread to
have to do something special now, better just check global state
in the very few places its needed.

On the unrelated note: better in an unrelated thread!
