 * Try to connect to a unix domain socket at `path` (if it exists) and
 * see if there is a server listening.
 *
 * We don't know if the socket exists, whether a server died and
 * failed to cleanup, or whether we have a live server listening, so
 * we "poke" it.
 *
 * We immediately hangup without sending/receiving any data because we
 * don't know anything about the protocol spoken and don't want to
 * block while writing/reading data.  It is sufficient to just know
 * that someone is listening.
