It might be nice to make Everything whenever possible, though I don't
really like the idea of not starting from a clean tree (build issues
related to files moving in the tree could slip through).  Note that
ccache can help reduce build times significantly.  If someone had it
working with the Everything target and a periodic World like before,
that'd be great though.

I'm not sure how this would work with the tinderbox scripts we have, but
it would be really useful.  Also, using cvsup to fetch the entire
repository is highly recommended if you're running more than one
