# TEST	rep052
# TEST	Test of replication with NOWAIT.
# TEST
# TEST	One master, one client.  After initializing
# TEST	everything normally, close client and let the
# TEST	master get ahead -- far enough that the master
# TEST 	no longer has the client's last log file.
# TEST	Reopen the client and turn on NOWAIT.
# TEST	Process a few messages to get the client into
# TEST	recovery mode, and verify that lockout occurs
# TEST 	on a txn API call (txn_begin) and an env API call.
# TEST	Process all the messages and verify that lockout
# TEST 	is over.
