distributed free working
-app sends a VMSSemReqst to his Master which send a request to a different Master
-Master send the request directly
-The request structure is freed by the sender, when the request was handled
There are still problems on shutdown. The shutdownVPs are all allocated by one Master which is likly to be terminated
