The /proc filesystem and associated ioctls has existed for quite some
time.  You should be seeing more commercial UNIX implementations with
such facilities.  (Silicon Graphics has been shipping one for over a

This is a false dichotomy.  The UNIX kernel can be reengineered to
properly handle such things, and in fact it has been.
