I'd need it merged into mainline at some point, unless anybody has strong
arguments against it.  All I can guarantee here, is that I'll back it out
myself in the future, iff Cpushare will fail and nobody else started using
it in the meantime for similar security purposes.

(akpm: project details are at http://www.cpushare.com/technical.  It seems
like a good idea to me, and one which is worth supporting.  I agree that for
this to be successful, the added robustness of Andrea's simple and specific
jail is worthwhile).
