Can not happen as long as libvirt hasn't asked for the exist status via
waitpid() because the pid is still in use by the zombie ssh process.
Hum, which is precisely why we need the patch. Still I would feel a bit
better if we could check that priv->pid is a child of the current process
something like (getppid(priv->pid) == getpid()) test before any kill would
do this easilly I think.
