* Prevent deadlocks in persistable channel pause test
Because of reuse of the old paused/resumed channels in this test there
was a potential for deadlock. This PR ensures that the channels are always
reobtained.
It further adds some control code to detect hangs in future - and it
ensures that the pausing warning is not shown on shutdown.
