Yes, I object. I would rather rip out the support in 'w'. This "feature"
was ill conceived and ends up making 'w' appear to hang all the time when a
nameserver is unreachable. This happens all the time on freefall and it is
more than a bit annoying. We've gotten bug reports about it too.
I would be willing to compromise, however. If you would like to make the
lookup an option rather than the default, I would have no problem with this.
'w' has a -n option to disable the feature, but I hate the feature being the
default.
