> In the new performance test framework, the ParticipantExecutor does these two things
at the end when the participant has completed:
> # Send the results
> # Tell the participant to release its resources.
> When this is done in the order listed, the client may receive a TEAR_DOWN_TEST command,
which causes the connection to be closed, while it is inside releseResources(). This provokes
the client deadlock reported in QPID-4276.
