I'm unsure why.  It happens even with verbosity set back to 1.

That sounds plausible.

After fixing a bug in dnssec-trigger-script that was causing it to
crash (TRUE -> True), the forwarders are now being set properly via
DHCP.  The behavior is the same either way--without any forwaders or
with one forwarder set to, a NetGear router with stock

I have a CeroWRT router that I'll test next--at least I should be able
to monitor the connection limit to see if that is the problem.
