No, the checksums are only computed for the files given to the -W option -- an

I don't need to "imagine" it -- it already happens :-) Every time you install 
a port, every file is checksummed and the sum is recorded.

My patch simply makes use of that information to make the `-W' option more 
useful.

Have I dispelled the "overhead" argument?
