    Added close destroy-method to Postgres data source. Example crashed and burned on master-slave
failover when master lost network connectivity - took down VM.

    Fix for AMQ-5294. Refactored tool to unify timing of the samplers and client (producer/consumer),
in such a way that the performance test no longer sits waiting for sampler to complete, even
though the run terminated much earlier. Full description of approach in http://issues.apache.org/jira/browse/AMQ-5294?focusedCommentId=14077910&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14077910

> I was using 5.9.0 and meet one problem so I tried to upgrade activemq. I tried both 5.9.1
and 5.10.0 and encouterred a same problem. I saw messages filled DLQ very quickly. I checked
the clients both producer and consumer but there was no error. I checked activemq log and
found the log is full of these warnings:

> The problem mostly happens right after activemq starts and sometimes happened after activemq
worked normally for a while.
> For now I have to roll back to 5.9.0 and the problem doesn't occure.
