I have a 6.2-STABLE snapshot box from August that where named(8) is
going into what appears to be a tight loop calling gettimeofday(). It
is using all CPU time on the box. It seems to be answering queries
alright, just using a lot of CPU.

I noticed a mention of a change in gettimeofday() handling in the
release announcement for 9.3.4-P1, and am wondering if that may have
something to do with the problem.

1990. [bug] libbind: isc's override of broken gettimeofday()
implementions was not always effective.

It could be that I just need to scrap that machine...
