Ah. Thats a good one. Probably. The expectance is, that the device 
immediately starts another poll after retrieving a result. But if there 
are processing constraints / connection interruptions and this cannot be 
met, it should not be fatal. After a timeout, the relay should stop. Or 
maybe after having a filled (not full) queue for a certain timeout. 
Depending on the trust (or deployment decision) between server and relay 
the relay could offer a receive queue with a depth of more then 0. And 
to the client of de service-over-relay the takedown-rebuild cycle should 
be transparant.
