To quote from bin/qrunner:

"Each named runner class is run in round-robin fashion. In other words, the
first named runner is run to consume all the files currently in its
directory. When that qrunner is done, the next one is run to consume all the
files in /its/ directory, and so on. The number of total iterations can be
given on the command line."

So, if I understand this correctly, if ArchRunner is the first named qrunner (the default), it will have to complete its run before an other qrunner will be able to process their queues. Is this correct? It seems a little backwards, since I'd guess that archives are usually the lowest priority queue. Can this ordering be changed by altering the QRUNNERS = [] array?
So, the qrunners _aren't_ really executing in parallel?

Because of the list locks, it'll only help if you're archiving
messages for a bunch of lists.  But if that's the case, it'll
definitely help (at the cost of more cpu) because ArchRunner --
actually all the qrunners -- can only handle one message at a time.
