TRQ-2083. Job status polling no longer exists. This information is received with the regular status update from the mother superior instead of as a separate, additionaly communication.
TRQ-2309. Make it so that node_spec() recognizes if the request specifies a list of nodes or if it simply is requesting a chunk of nodes. When it is a hostlist, as is most common if you're using a scheduler, it can be 40% faster to use this method instead of searching linearly as used to be done. This number can vary upwards or downwards depending on the size of the job, number of nodes in the system, and usage of the system. The 40% faster was found running single node jobs on a relatively idle system with 3k nodes. Larger systems that are under heavier stress may see a larger speed-up. Running jobs using many nodes might not see as much speed-up, although it should still be faster. This will save acquiring any unnecessary mutexes, so at peak usage times the speed-up might be far more than 40%.
