Avi, please dont put arguments into my mouth that i never made.

My (clearly expressed) argument was that:

_a new guest-side demon is a transparent instrumentation non-starter_

What is so hard to understand about that simple concept? Instrumentation is
good if it's as transparent as possible.

Of course lots of other features can be done via a new user-space package ...

Thanks,

Ingo
