+# This test attempts to catch a race condition between autocommit
+# transaction and transaction which is rolling back due to
+# deadlock.
+#
+# Since it is trying to catch a race condition which may not reliably
+# occur, several runs are necessary for certainty. Hence the body of
+# the test was placed into the .inc file and sourced several times below
+#
+# Test outline:
+# * Trx 1a makes updates
+# * SR trx 1b writes a row 3, then makes updates
+# * AC trx 1c will attempt to write row 3 and will wait for lock
+#   held by 1b
+# * Sync point is set for 1b to delay SR rollback
+# * SR trx 1b makes an update which makes it conflict with trx 1a
+# * Slave shows BF - BF conflict and fails in applying write event
