Oh, and the real question, which i forgot to ask - for those
who objected to Cedric's patchset on the grounds of lack of file access
controls, does this patchset address your concerns?

It seems to me it provides isolation to those who want it, while leaving
the door open to a uid mapping solution (whether in a stackable fs, a
global-uidaware fs, or whatever) in the future.
