[Martin Sivak]

Hello Adam Litke,

I'd like you to do a code review.  Please visit

to review the following change.

Change subject: Balloon should not work when guest agent is not present
......................................................................

Balloon should not work when guest agent is not present

StatAvg returns 0 when there is no data available. We need to use Stat
here so we get None and properly fail the condition.
