[Bug 1859011] Re: bounce mail processed multiple times -> oom crash of BounceRunner

Each object in the bounce events is a 4-tuple like (list-name, bouncing
address, bounce date, bounce message). The bounce message is a
Mailman.Message.Message object, but should be and apparently is rendered
as the text of the message. So yes, the third line is the bouncing
addresses, and it is clearly corrupted, but I suspect that is a symptom,
not a cause.
I still don't really understand what's happening. Given that the message
contained a large PDF attachment, I suspect this isn't a real bounce,
but rather is spam sent to the list-bounces address or possibly a list
post mis-sent to the list-bounces address. The size of it may have
something to do with the corruption that occurred, although I still
don't understand how the duplication comes about.
What's in Mailman's bounce log from the time this happened. I'm
particularly interested in any 'bounce message w/no discernable
addresses' or other messages just before the "Dec 30 19:53:29 2019
(13392) <BounceRunner at 140395473885088> processing 4134 queued
Also are there any "VERP_PROBE_REGEXP doesn't yield the right match
groups:" messages in Mailman's error log from this time.
