Okay, there are several things being mushed together here.  Let me see if 
I can sort them out:

1) ad.doubleclick.net doesn't handle AAAA requests properly

Solution: complain to ad.doubleclick.net

2) There is no global way to make IPv6 go away in kernel, world, and ports

This seems to be a FreeBSD bug.  The intent with the ability to remove
IPv6 from the kernel config and set ipv6_enable to no would seem to
indicate that somebody wants to be able to shut off IPv6.  The fact that
the resolver still executes an IPv6 request would appear to be breakage.

3) Mozilla/Konquerer/whatever completely hangs during the timeout period 
on the AAAA record request

*Whose* bug is this?  Is this a FreeBSD bug or a Gecko bug?  Or both?  
And, if it is a FreeBSD bug, where is the bug?  The main dns resolver or 
the ports makefile?

4) How is anyone short of guru status supposed to connect "Mozilla chokes 
on FreeBSD" with "the DoubleClick DNS server config is broken"?

If this behavior is indeed deemed "not a bug", then some piece of
prominent documentation needs to explain this for idiots like me.

Have I missed anything?  I am asking these questions so that I can file 
the appropriate bug reports.
