svn commit: r916751 - in /qpid/trunk/qpid/cpp/src/qpid: cluster/Cluster.cpp cluster/ClusterTimer.h cluster/Cpg.cpp sys/AggregateOutput.cpp

Author: aconway
Date: Fri Feb 26 16:47:23 2010
New Revision: 916751

URL: http://svn.apache.org/viewvc?rev=916751&view=rev
Log:
Fix cluster abort on shutdown in ClusterTimer::fire.

The cluster destructor was not deleting the ClusterTimer set on the
broker, so this timer had a dangling pointer to the cluster.
