result := vm.WaitResponse()
send event to ctx.HUB
[ the vm loop handles the event and sends a response event back,
[ but vm.GetResponseChan() in the vm.WaitResponse() might be
[ later than the response event, and the response event will not
[ be caught, and the next statement will deadlock ]
<-result
fix it by moving vm.GetResponseChan() up (out of the go routine).
