I don't have an eta for finishing up job arrays, they are a high priority,
but we are a little short handed right now.  I need to finish up some BLCR
checkpoint/restart stuff that another TORQUE developer had started. Then I
think I will focus on squashing a few bugs that I've heard about. Then once
things are stable I can turn my attention back to job arrays.  Hopefully by
the end of the summer they will have all the functionality you need.
