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