OK - I think I may have narrowed down what's going on, and it looks like it
could be down to a checkpoint attribute which is set to 'u' on all jobs by
default for some reason. The qsub man page doesn't document the 'u' value,
so I've set it to 'n' instead (which it says means no checkpointing) and
released the scheduler hold on the job.
I'm pretty sure Moab is not the issue, it's happily picking whatever nodes are
free to try and run the job, but Torque (1.2.0p5) is rejecting it because:
