Next step: remove the wait-handle list. The server can be stopped and restarted with the DB backend. Wait-handles are not a good fit for this design. It would probably better to go back to polling results from the distributed engine. With a kind of polling operator it would also be possible to persist the distributed engine while jobs are running on the grid and later resume the engine.
