+# This test case starts the slave server with: 
+# --relay-log-space-limit=8192 --relay-log-purge --max-relay-log-size=4096
+# 
+# Then it issues some queries that will cause the slave to reach
+# relay-log-space-limit. We lock the table so that the SQL thread is
+# not able to purge the log and then we issue some more statements.
+#
+# The purpose is to show that the IO thread will honor the limits
+# while the SQL thread is not able to purge the relay logs, which did
+# not happen before this patch. In addition we assert that while
+# ignoring the limit (SQL thread needs to rotate before purging), the
+# IO thread does not do it in an uncontrolled manner.
