# TEST lock006
# TEST Test lock_vec interface. We do all the same things that
# TEST lock001 does, using lock_vec instead of lock_get and lock_put,
# TEST plus a few more things like lock-coupling.
# TEST 1. Get and release one at a time.
# TEST 2. Release with put_obj (all locks for a given locker/obj).
# TEST 3. Release with put_all (all locks for a given locker).
# TEST Regularly check lock_stat to verify all locks have been
# TEST released.
