     223 * WORK_REQ has fields for requests (secs, instances) of the various resource types
     224 * WORK_REQ has a field no_gpus indicating that user prefs don't allow using GPUs
     225 * WORK_REQ has a field '''rsc_spec_request''' indicating whether it's a new-style request
     226 * for new-style-requests work_needed() returns true if either additional seconds or instances are still needed
     227 * add_result_to_reply() decrements the fields in WORK_REQ
     228 * get_app_version(): if we first chose a GPU version but don't need more GPU work, clear the record so that we can pick another version
     229 * get_app_version(): skip app versions for resource for which we don't need more work.
