So in theory should be good.

Unfortunately although its happening a lot its taking the
large numbers of machines to make it that way.
Over the 130+ machines we're seeing between 3 and 8 panics
a day, so based on that we could be waiting quite some time
for a specific machine to panic :(
Don't think we're going to make any progress on this in the current
state so I think we'll give it a shot.
