	I did some minor testing and the problem seems to occur after 
looking up five to six sites in a row.  The sites themselves don't 
matter.  An example, I'll go to www.netbsd.org, then www.apple.com, and 
then 3 or four more different sites.  By the fifth or sixth site, the 
DNS lookup takes about 30 seconds to a minute.  It is almost like it is 
timing out using some option, and then finally doing the resolution.  
This could quite possibly have something to do with IPv6.  I noticed 
some strange things happening when I did a couple package adds through 
ftp.netbsd.org.
	At any rate, is there something I can do to check and see what the 
problem is?  I ran ipfstat -t during the testing to see if my ruleset 
was the problem, but nothing stood out.  Should I maybe disable IPv6 
support in the kernel?  If I do this, sendmail complains.  I just 
finished finals week so I have some time to do testing of all sorts. : )
