# TEST	si006
# TEST
# TEST	Test -immutable_key interface.
# TEST
# TEST  DB_IMMUTABLE_KEY is an optimization to be used when a
# TEST	secondary key will not be changed.  It does not prevent
# TEST 	a deliberate change to the secondary key, it just does not
# TEST  propagate that change when it is made to the primary.
# TEST	This test verifies that a change to the primary is propagated
# TEST	to the secondary or not as specified by -immutable_key.
