I have several hosts back on credit2, no problems so far.  But the
bulk of my production hosts are still on credit1, and they do seem to
run "better" (subjectively, looking at responsiveness and load
averages) but of course by subjectively I mean that I have no real
data to back this feeling.

I was hoping one of my domU's on credit2 would crash so I could grab
debugging info for the development team - I hope you are/were able to
grab and submit data on that crash???
