# Test:
# 0. The test requires two servers: M1 and M2.
# 1. Create a table on server1 and insert 71000 rows on it.
# 2. Assert that a conflict between a huge transaction, one that
# does change all table rows, and a small transaction is
# detected.
# 3. Assert that the remote transaction was the applied on both
# members.
# 4. Clean up.
