Have you considered destroying and recreating driver domains rather than
sleeping them? They are stateless after all, and should be quick (enough) to
boot.
We want to support driver domain restart anyway for driver-bug isolation.
The question mark there is whether we have the xenbus protocol sorted out
yet to allow frontends to automatically reconnect. You don't even have to
worry about that if you're prepared to do lightweight suspend/resume of all
non-driver domains across S3.
