# Test locking of a tuple with a committed key-update. In this case,
# the update conflicts with the lock, so failures are expected, except
# in READ COMMITTED isolation mode.
#
# Some of the permutations are commented out that work fine in the
# lock-committed-update test, because in this case the update blocks.
