Is xentop accurate? Can it be 100% relied upon its CPU usage and other statistics?

Clearly there is a lot going on besides what the CPUs of dom_0 and dom_U see in their own realm.

Thanks, any heuristic or anecdotal information would be also of interest, if there is no gospel from the authors/care-takers of this code.

(There is some thread from 2010 http://old-list-archives.xenproject.org/archives/html/xen-devel/2010-08/msg01197.html, and some older threads that refer to accuracy issues with Xentop. I don't know if there is some truth to these threads.)

(Sorry, I have not looked at the code).
