# TEST	rep071
# TEST	Test of multiple simultaneous client env handles and
# TEST	upgrading/downgrading.  Tests use of temp db handle
# TEST	internally.
# TEST
# TEST	Open a master and 2 handles to the same client env.
# TEST	Run rep_test.
# TEST	Close master and upgrade client to master using one env handle.
# TEST	Run rep_test again, and then downgrade back to client.
