No, I'm not talking about actually implementing waitpid, but just adding
some utility functions for handling multi-processing in a bit more
convenient way.  Starting a process and then waiting until it's done
isn't an unusual thing to do, so a wait-for-process function would be
nice (in this instance).

In general, it would be nice if Emacs grew a rich feature set for
synchronisation (thread and process), perhaps based on futures (or
whatever kids these days are using).
