Not exactly.  You're forgetting that mailmanctl is the usual way to
start all the qrunners going, and it forks a separate process for each
queue.  It actually invokes bin/qrunner with a separate -r option each
time.  So in normal operation, they do all run in parallel.

Since they are running parallel, it doesn't make sense to change the
order, but what you /can/ do is change the SLEEPTIME for ArchRunner so
that it doesn't try to run once per minute.  Currently you need to add
something like

    SLEEPTIME = mm_cfg.minutes(5)

just under the "class ArchRunner" in ArchRunner.py to change this
