If someone knows what the deal is with this, I've been ripping my hair
out for the last few versions of VirualBox.  There is some discussion
about this at:  http://forums.virtualbox.org/viewtopic.php?f=1&t=22750

Truth is, I'm starting to wonder if this is a hardware problem on my
end...but then people like yourself and others in that forum thread
are reporting the same issue.  I don't know what to think.

>From a development point of view, is there some way to get additional
logging as to what VB is doing when the guest is (supposedly) sitting
there idle?  Would be nice to know where the tight loop is happening.
I see absolutely night in my machine log while it sits there consuming
100% of the cpu.
