Maybe you can tell us a bit more about the framework you're using to launch processes at the remote end?

If you don't want to poll, and can't use wait, maybe you can have the process at the remote end (or a wrapper around it) send you a message when it has finished?

    This is normally what remote-procedure-call mechanisms do: the host runs the request, waits for it to finish, and sends a completion-status message back to the client. The client only needs to wait for messages and to interpret them when they arrive. If you want to give a "progress message," a timer is the way to do that. (Turn off the timer once the completion-message arrives.)
