+Subject: Bug #10489: Don't retry unix socket connect()s on ENOENT.
+
+If the socket isn't there, it's not gonna magically appear.  Either it's
+a server socket and you should have just waited for the SIGUSR1 from the
+server, or it's a stale reference to an ICE socket.
+
+However, do retry once, so fallback from abstract to filesystem namespace
+works.
+
+Originally Debian bug #385976.
