app.systemStatus() and app.serverTest()

Hi folks

1. Does anyone know if its possible to read the system status values while a second JavaScript is running on the server in parallel or does the InDesign Server just queues the jsx calls, files send by a SOAP request?! Means can I watch the Server status by a second script or just within the currently running script.

for(x in ServerStatistic) {
  app.consoleout(x+":"+app.systemStatus(ServerStatistic[x]));
}

2. Does anyone know how to use the method app.serverTest(/**String*/ testName)? What kind of name should be provided to run what kind of test. Is it a name of another jsx file or c++ class or ...?

Cheers Tino
