sometime forcing oneself to describe a problem is the first step to a
solution. I just realized that I also had an autocommit statement in
my config with the exact same amount of time the seemed to be between
the warnings.

I removed that, because I don't think I really need it, and now the
warnings are gone. So it seems it happened whenever my manual commits
overlapped with an autocommit, which, of course, was more likely when
many commits were issued in sequence.
