This is all fine and dandy discussion, but I really don't see that Apache
should or would build in facilities that are dependent upon running as
root. We explicitly discourage that behavior, we check for it, and we even
force the package to do extra legawork (-DBIG_SECURITY_HOLE) if they want
that.

So given all the push against running as root, why would the server grow a
lot of functionality to run in that particular mode of operation?
