I'm not sure what you mean with `ripping up the libc library once
again'.

Neal developed the concept of object handles, which can be implemented
on top of both L4 and Mach, and provides everyting we currently use
ports for.  You can read more about it in the archive of the l4-hurd
mailing list, for example in
<http://mail.gnu.org/pipermail/l4-hurd/2002-October/000692.html>
and other messages in the same thread.
