BUG#25463 (Memory allocation problems in replication slave thread):

The problem is (most probably) caused by whole server shutting down before a 
slave thread terminates correctly. Fixing this requires fixing server shutdown
code which has been done in 5.1 tree. Thus we ignore the issue in 5.0 assuming 
that it is fixed in 5.1.
