I think I've decided to try to push it.  I'm working with some patches
at git://
(branch p9auth.jan3.4 is latest).  I'll send patches as I feel they
are ready - so far they pass testcases, but are too new for me to
feel I should push them today.

Ashwin, I'm curious whether you'd think the last patch
would be a problem with any userspace - but I assume there is no
legacy userspace to really worry about?

Apart from plenty more cleanups, another more fundamental issue to
address is how to stop unused caphash entries from piling up in
memory.  Put a timeout on them?  Let privileged userspace list and
occasionally delete them?  Associate a target task with each entry,
where either the task or its decendent can use the capability, but
if the task dies we free the caphash entry?
