# TEST Run a modified version of test001 in a replicated master env.
# TEST Run in replicated environment with secondary indices too.
# TEST Make additional changes to master, but not to the client.
# TEST Downgrade the master and upgrade the client with open db handles.
# TEST Verify that the roll back on clients gives dead db handles.
