I think a message should appear when RES_OPTIONS=debug is set.

I'm a bit puzzled at all the clamoring for this change. Why don't
people simply run local caching resolvers? It's far better on the
network (though increases the memory footprint some).

If we're actually going to propose a filesystem access on every
nameservice check (i.e. fstat() or lstat()), I think that is not an
appropriate change if it is mandatory, and it should be controlled by
an option. I'd also like to have a better understanding of its
performance effects, especially on slow machines.
