I've just reread the description of -odq and certainly can't fault
the documentation. I can only guess that I stopped reading after
"local deliveries are done in the normal way" and assumed that the only
difference between -odq and -odqs was the handling of local addresses.
Silly.

I've got a screaming fast DNS setup, with a local caching resolver that
uses a wide pipe to a beefy upstream forward, but is quite prepared to
do its own dirty work when the upstream forward gets sluggish.
When you speak of resources, you're just talking about DNS lookups and a
bit of IO on the hints db, right? I'm pretty sure it's not going to be
a problem; I'm just wondering whether I'm in for any surprise resource
consumption.
