Yes - it goes absolutely insane. I watched it get 40 points behind in
3 games in a money session, both sides playing expert mode.

In external.c, the actual playing function for the server is quite
short. I suspect that when it goes to evaluate cube decisions, that it
doesn't set the context up correctly to get the cube info - it's even
possible that it's getting it for the wrong side or something. I
emailed Joern about this as I think he knows the cube eval functions
better than most.

There's a minor bug in this routine in that it doesn't know about
optional plays.

There's a bigger bug - if you start the master in graphical mode,
every time I attempt to quit from the master, it takes down my X
server, which is fairly annoying. Running the server in text mode
doesn't do this.
