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.
** Changed in: linux (Ubuntu Saucy)

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.
