Doesn't look like it helps when the backlog is associated with only one particular high volume list, as it seems (by looking at the /locks directory) that only one qrunner can operate on a given list at a time.
The other ArchRunner is basically idle. However, it might help if the qrunner tasks for one particularly high volume list were impacting performance for other lists.

I recently upgraded from mailman 2.0.12 to 2.1b3 and am quite pleased
with the new qrunner setup (among other things).  We have one
particularly high volume list with very bursty postings (since the main
poster is scripting postings).  In mailman 2.0.12 we'd often have
hundreds of files stuck in the qfiles directory, sometimes for hours.
Now, postings go through much more quickly.  However, archiving still
lags quite a bit, and that qrunner has _very_ long run times:

mailman  5476 93.5  2.7 32188 31388  ??  R     4:18PM 115:01.18 qrunner
/home/services/mailman/bin/qrunner --runner=ArchRunner:0:1 -s (python)

I'm pretty sure lag in archiving is what was causing the whole thing to
back up in 2.0.12.  So, although the backlog is now mostly isolated to
archiving (a very good thing) I'm looking for a solution to fix that.
Not archiving is not an option.  Should forking more ArchRunners help
with this, or will this just cause more contention?

My platform is FreeBSD 4.6-STABLE on a 700mhz PIII with 1GB RAM, running
mailman 2.1b3 with Exim 4.05.
