When you say 'xhost +localhost' you're also granting permission for 
applications to connect throught the unix domain socket.  On a system with 
Unix domain sockets, it's hard to see a valid use for 127.0.0.1:6000.

This is in no way meant to disuade people from adding suitable options to 
configure which interfaces the (deprecated) IP listening sockets should 
bind to; I think that's a very useful idea.  I'm just trying to show that 
the need for any IP connections is even less than people imagine.
