`scan_sexps_forward'.

tests are running, to avoid interfering with our thread counts.
* test/src/thread-tests.el (threads-test-condvar-wait): Use
with-mutex instead of emulating it inline.
(threads-condvar-wait): Improve comments. Check that the new
thread is alive before waiting for it to become blocked on the
conditional variable.

attempting to lock the mutex, to make sure the lock's owner is
recorded correctly.

the emacs-buildstatus list. (Bug#24503)
