thanks for the courtesy copy, thomas, and for freeing up the queue!

on the pre-Saga systems, there used to be a limit on the number of jobs a
user could have in the queue, 200 maybe.  it sounds as if Saga does not
impose such a limit (currently)?

artur, i once wrote a script to ‘trickle’ very long lists of jobs through
the scheduler, while keeping my count of jobs in the queue below some limit
at all times:
