# Scenario:
# SigCon connects to slave and creates some lock on a record,
# and tries to commit, but pauses just before a check for is_aborted.
# Master changes the same record
# Applier thread (which is boosted to High Priority) tries to modify
# the same row Master has modified, but observes the lock created by
# SigCon, and decides to abort SigCon.
# SigCon becomes unpaused, notices it should abort.
# There was a bug in that SigCon client observed success, despite
# the transaction being aborted.
# no need to rerun this test three times
