Thanks for the change log Daniel.

Something is solliciting my curiosity though:

  - privacy for guests, which will hide things from xid 1

I am not sure I am found of that "privacy" thing. Isn't xid 1 the
monitoring context? Isn't supposed to be able to see everything in the
system? For instance, if I remember correctly, vserver-stat uses xid 1
to mesure the memory usage of each vserver...

Maybe it's an irrational fear, but it seems to me like an invitation to
root kits... With this privacy option, how will we be able to precisely
account the memory usage of each vserver?
