+# $loop_rounds times and checking if the changes to values caused by the action
+# are reasonable.

+# Requirements:
+# 1.  Have socket_summary_by_instance_func running
+# 2a. Have a connection con1
+#     @con1_object_instance_begin needs to be the OBJECT_INSTANCE_BEGIN
+#     value of the "client_connction" entry belonging to con1 within
+#     socket_summary_by_instance.
+#     $statement needs to contain the statement to be executed by con1.
+# or
+# 2b. Have assigned values to the following variables
+#        $connect_host $connect_db $connect_user
+#
