# TEST rep015
# TEST Locking across multiple pages with replication.
# TEST
# TEST Open master and client with small pagesize and
# TEST generate more than one page and generate off-page
# TEST dups on the first page (second key) and last page
# TEST (next-to-last key).
# TEST Within a single transaction, for each database, open
# TEST 2 cursors and delete the first and last entries (this
# TEST exercises locks on regular pages). Intermittently
# TEST update client during the process.
# TEST Within a single transaction, for each database, open
# TEST 2 cursors. Walk to the off-page dups and delete one
# TEST from each end (this exercises locks on off-page dups).
# TEST Intermittently update client.
