Subject: Performance fix for ssh X11 forwarding: turn on TCP_NODELAY on local
 stub connections on client and server side.  (it was correctly being enabled
 over the long-haul connection, but somehow it got missed on the loopback
 connections to the real X client and server)

This makes x2x over ssh actually pleasant to use.
