This seems to be the preferred method of calling out to usermode these days for seldom-called upcalls. It's simple and doesn't require a running daemon, so it should "just work" as long as the binary is installed. The client tracking exit operation is also changed to check for a NULL pointer before running. The UMH upcall doesn't need to do anything at module teardown time.
