Except that SysV-based systems allow 'chown' to anyone, even root.

I could create a script that does something nasty, place it in my directory
and then 'chown' it to root, and I'm golden.

The way CGIWRAP does this is that it looks only in that person's
directory, makes sure that the directory and the file are owned by
the same person (and even same group if you want) and only then
executes. Thus, to run a 'root' script, I need to be able to write to
roots HOME in the first place to plop my script there.
