From 48d4d34689c3fb8b0ba25f775b34ca5472568a33 Mon Sep 17 00:00:00 2001
From: Horst Hunger <horst@mysql.com>
Date: Wed, 11 Feb 2009 10:27:52 +0100
Subject: [PATCH] Reviewed fix for bug#40882: Replaced "sleep 1" by
 wait_condition, added save/restore start values and closed open sessions.
 When trying to use "wait_for_query_to_succeed" a type has been fixed, also in
 "rename.test": Added session count and check and replaced error numbers.
