IIRC, there was partial support for gid= on procfs in stock 2.4 kernels,
and -ow patches completed that.  Is this somehow gone in 2.6?  (I did
not look into this at all.)

Where is this code (your changes)?  Just on your computer?

Not done yet?  (At least, I was not CC'ed on a message like that.)

What exactly do you mean by "hiding /proc pid directories"?  Restricting
the perms on them (like in -ow patches and grsecurity) or actually
hiding the directories themselves (not revealing the PIDs and their
corresponding owner UIDs)?

You haven't started this discussion yet, have you?  Where do you intend
to discuss this (owl-dev, LKML with some CC's)?

Sounds fine, although of little relevance to Owl.
