- Close a race where a thread on another CPU could release a contested lock
and empty its turnstile while the blocking threads still pointed to the
turnstile. If the thread on the first CPU blocked on a lock owned by
one of the threads blocked on the turnstile just woken up, then the
first CPU could try to manipulate a bogus thread queue in the turnstile
during priority propagation.
- Update locking notes for ts_owner and always clear ts_owner, not just
under INVARIANTS.
