08c3888312 make a long running operation terminate if the client has disconnected. we check for this at the beginning 
of every request but intra request.  if a request will run for a very long time this is bad.

probably not for backporting -- might be nuances need to smoke for a while

also some yield code cleaning, really just making it easier to read.
