+# Inject two group commits. The bug was that ANALYZE TABLE would call
+# wakeup_subsequent_commits() too early, allowing the following transaction
+# in the same group to run ahead and binlog and free the GCO. Then we get
+# wrong binlog order and later access freed GCO, which causes lost wakeup
+# of following GCO and thus replication hang.
+# We injected a small sleep in ANALYZE to make the race easier to hit (this
+# can only cause false negatives in versions with the bug, not false positives,
+# so sleep is ok here. And it's in general not possible to trigger reliably
+# the race with debug_sync, since the bugfix makes the race impossible).
