This one did the trick. Thanks again, this was _very_ helpful.

I have identified the source of my issues: It turned out that the
Mailman installation I inherited was more heavily modified than I
thought - and one of those modifications was the source of the issue I
described. I decided to permanently take care of this and did a clean
reinstall, followed by artitifical stress testing and as expected, the
problem vanished.

I apologize for the noise my inquiry caused.
