* Clients overload UGen::new1 , this gives a mehod we can pass a blocking arg to without cluttering kr, and puts all arg checks in one place.
* Blocking calls are done with processBlocking
* FluidBufCompose always blocks
* NRT process calls new1, not kr
* some server.syncs removed to lessen dilly dallying
* completion is triggered by /done message from server, matched against nodeID. replyID indicates status
* changes to NRT SC Wrapper makes it a UGen, using the RT thread for polling and delegating to SC NRT thread for launching
* changes to FluidBufNMF: Now a UGen with kr (emitting progress updates); process() wraps .kr via Function.play. Sync at end managed through use of doneAction
* TODO: cancelling, checking progress, all the other client (and then the help...)
