Just for the record, I run about 13,000 lists on one server, with a total of
261,000 subscribed Emails (137,000 unique) and haven't yet had reports of
such problems.
However, I just checked and my biggest list only has 4611 members, but I'm
not sure that list size would really make that big a difference, while exim
is fast, it can't always deliver 4,000+ emails in less than one minute, so
every so often, one of my queue runner runs past its minute timeslot, and
I've never seen problems.

My guess is that it may be a problem with qrunner locks, but having played
with that code a bit (and debugged qrunners that were running too long
mostly due to pipermail html archiving), I've not seen any problems with the
locking.
The one thing that does worry me a bit, is seeing these every so often:
