Hrm. I've seen truly excessive DNS traffic for quite some time now
with -current on a variety of architectures (macppc, i386, mac68k).
Is that the kind of thing you're seeing too?

It seems like we're hitting DNS servers way harder than we need to
be, not caching anything for responses from the resolver library...

Can't say I've had that happen. My main macppc machine is way back
at 1.5.3_ALPHA, but I was using a 1.6-current releng snapshot on a
macppc as a firewall/gateway for a while and I didn't see anything
resembling that. (But I only had 608/128 ADSL at the time and wasn't
generating a lot of local traffic, so it's possible I didn't get
close to peaking anything.)

Maybe worth my trying ab on my 1.5.3_ALPHA before and after upgrading?
(I'm in the act of crossbuilding a netbsd-1-6 checkout from this
evening for it.)

Or is this only with -current?
