Should use same RalphGlobals on the same host.  This is because each RalphGlobals listens on a TCP port for servicereference connections.  If do not use the same ralph globals, then need to explicitly provide alternate port for RalphGlobals to listen on, or we get an address-already-in-use exception.
In SingleControllerFairness test, had been ignoring command to use
wound-wait instead of Ralph fair-scheduling algorithm.
