An alternative is to use a persistent ssh connection, reusing the X11 
token from before.

BTW, an incantation of:

     ssh host 'x11-client &'

has some scope for dropping the ssh before the client hooks into X11 
(thus keeping things open) _if_ the client closes its own output before 
connecting to X11. WHich on reflection would be vanishingly rare, since 
then it wouldn't get to report failure to connect :-)

Shouldn't the new xauth setup be just fine, though? THe sequence should 
be:
- ssh in
- xauth setup on host end
- x11 client connect, _using that new xauth_

I find the xauth scenario a little unconvincing because of this. I'm not 
in a position to try to reproduce things though.
