That's pretty difficult to trigger remotely, and the last time
we saw a legitimate case of this it was actually a bug in the
Linux TCP stack which we've long since fixed.

I would rather not let people easily disable this, since it
finds bugs and I can't see someone seriously exploiting this
to spam your logs.

I suppose you disagree :)
