> When the executor asks the daemon to spawn a new worker, the executor tries to establish a connection without any timeout mechanism. If the worker has some issue and hang before it can establish a connection with the executor, the executor will hang there forever.
> We have a timeout mechanism for simple workers, and we should have a similar mechanism for daemon based workers.
