 I was under the impression that that dhcpcd patch I originally tried
 is why dhcpcd recovers properly from the error, but that it was not
 going to be pulled into netbsd-8.  Have I missed something?

 I want to test netbsd-8 as it will be.  To check, I did a "cvs up" on
 the netbsd-8 tree where I reverted the dhcpcd patch.  Nothing got
 updated in the dhcpcd source tree, so I believe that I am testing
 netbsd-8 as it is.
