# TEST
# TEST	Start an appointed master and one client with 2 site strict
# TEST	majority set. Shut down the master site, wait and verify that
# TEST	the client site was not elected master. Start up master site
# TEST	and verify that transactions are processed as expected.
# TEST
# TEST	Run for btree only because access method shouldn't matter.
