[gridengine users] Determining why a job is in hqw

[William Hay]

We just got bit by https://arc.liv.ac.uk/trac/SGE/ticket/802 and it
took me a lot longer to figure it out than it should have in part
because there does not appear to be any indication when a job has an
array dependency on another job (at least in 6.2u3 which we're using)
All holds and dependencies just change the state to hqw  apart from
-hold_jid which shows up if you run qstat -j on the job.  So does
anyone have a technique for determining why a job is held
(other than running qstat -j to detect hold_jid and experimentally
releasing other holds to see what happens).
