Re: server won't exit when a streaming connection is active

That looks like it does get the Stop method to be called but it still hangs 
on the "Engine bus stopping" and won't continue unless you close any active 
connections in the browser. Is there a way to override this so that it 
doesn't have to wait for there to be no active connections?
