# TEST rep013
# TEST Replication and swapping master/clients with open dbs.
# TEST
# TEST Run a modified version of test001 in a replicated master env.
# TEST Make additional changes to master, but not to the client.
# TEST Swap master and client.
# TEST Verify that the roll back on clients gives dead db handles.
# TEST Rerun the test, turning on client-to-client synchronization.
# TEST Swap and verify several times.
