-1. It's worked like this for the last fifteen years or thereabouts,
and you're the first one to complain. I suspect some weirdness in
your logging setup, rather than any systemic problem that we
need to lobotomize our diagnostic output in order to prevent.

(The reason I say "lobotomize" is that there's no particularly good
reason to assume that the first N lines will tell you what you need
to know. And the filter rule would have to be *very* stupid, because
we can't risk trying to allocate any additional memory to track what
we're doing here.)
