Hmm, I think this is likely to confuse users that actually
do that, a lot.
One idea would be to either warn about, or even disallow user
initiated writes to readonly sections if trust-readonly-sections
is enabled.
But a better one would be to mark a written section (or memory
block/range) as "tainted", and then trust-readonly-sections would
not trust it anymore.
