You'll also need to remember that there's no live migration or
suspension of zone processes.
For those that need more resiliency, it's better to focus on
application level loadbalancing and failover than depend on the
underlying infrastructure for help. This is the approach that Joyent
adopt, and also one which lends itself to horizontal scaling (where
you add more zones over a number of boxes).
