Or you can construct a human-readable 404 page. Google will notice it says
404 and not index it, but a browser will show a nicer error msg than just
"not found".

IIRC, custom error pages in apache does that. If not, it can certainly be
done with simple PHP - we do this for wwwmaster.postgresql.org to deliver
"not found" pages inside the graphical framework. (originally they didn't
have a 404 code though, which caused the mirrorer to pick them up, and
google to index them, which wasn't a very good idea :-P)
