This change backs out some of the recent PVM launcher changes, though it
leaves the possibility open there's a running daemon to begin. It turns out,
error_exit wasn't working as I'd expected, and the daemon could get into
a funny state on a timeout (w.r.t. the socket addresses) regardless of how
the exit worked.
