One of the first things BIND does, if I'm reading lib/dns/zone.c correctly, is
to attempt to lock the keys, and if it fails it emits that diagnostic.

Assuming the signing is being attempted simultaneously in both views, I wonder
if that goes hand-in-hand with what Matthijs writes:

So maybe using the same key directory (from the same dnssec-policy) is actually
causing the issue?
