I've correlated this with wakeup activity in compiz. This issue seems to
have been resolved around 12th June 2013 and we've not seen any more of
these peak in wakeups since. So I'm going to mark this as fixed
released, I'm not sure what got fixed though.

Title:
  eventstat shows high number of events from swapper

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Saucy:
  Fix Released

Bug description:
  Looking at
  http://reports.qa.ubuntu.com/power/eventstat/image/14/machine/1/task_type/all/details/
  it looks like swapper is producing about 15000 events per minute
  during an idle eventstat run.  The raw results can be found at
  https://jenkins.qa.ubuntu.com/job/eventstat-saucy-desktop-amd64
  -install-idle-vm/4/?

  During raring, we were seeing much lower numbers.
