Even if so, it does not scale *at all*.  So, in Linux or even FreeBSD,
maybe, but I wouldn't want an ugly hack like this in NetBSD!

Isn't it exactly the kind of things NetBSD has been avoiding?  "Well,
it works _for me_" kind of hacks?

Oh, I wouldn't mind if someone made such a thing publically available
as an unofficial patch, provided that its users knew what they were
doing.  But, no, please not in the CVS tree.
