running strace on one of the treads shows the culprit:

poll([{fd=4, events=POLLIN}, {fd=8, events=POLLIN}], 2, 3998) = 0 (Timeout)
inotify_add_watch(8, "/etc/gdm", IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR) = -1 ENOENT (No such file or directory)
poll([{fd=4, events=POLLIN}, {fd=8, events=POLLIN}], 2, 3996) = 0 (Timeout)
inotify_add_watch(8, "/etc/gdm", IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR) = -1 ENOENT (No such file or directory)
poll([{fd=4, events=POLLIN}, {fd=8, events=POLLIN}], 2, 3996) = 0 (Timeout)
inotify_add_watch(8, "/etc/gdm", IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR) = -1 ENOENT (No such file or directory)

for some reason it is polling every 4 seconds and adding a watch on a
non-existent /etc/gdm directory

Title:
  accounts-daemon is progressively causing more wakeups over time

Status in The Ubuntu Power Consumption Project:
  New
Status in “accountsservice” package in Ubuntu:
  New

Bug description:
  Over the past few months accounts-daemon has been increasing the
  number of wakeup events it generates, see:

  http://reports.qa.ubuntu.com/power/eventstat/image/2736/machine/1/task
  /accounts-daemon/details/

  In April 2013 it was averaging about 13.5 wakeups per minute, now it
  has increased to 17.5.  This isn't much overall, but it does seem like
  the trend is upwards and every wakeup takes the CPU out of deep sleep
  and hence consumes a little more power.
