Cool, Tim has ripped out all the libssh code (which caused me issues at
${JOB-1} because it didn't play nicely with SSH keep alive messages) and 
replaced it with native handling inside Slurm using munge for

This bug has the explanation:


# Our X11 forwarding implementation cannot connect to unix sockets
# at this time

They point out that you can just do:

ssh -X localhost

to get an environment where it'll work.  Not ideal but better than the 
other workaround which is to disable the built in X11 forwarding and use 
the older spank plugin instead.

All the best,
