Yep, you've understood it correctly.  If the OpenRadar page is right
about it being an NXDOMAIN answer that causes the problem to manifest
itself, I would consider it to be a resolver bug instead of an OS X bug.

But, like I said, it's possible that the report just mixed up NODATA
with NXDOMAIN.  In that case it would most definitely be an OS X bug.
