accounts-daemon is polling frequenly on phablet images

Running today's image on a Samsung Galaxy Nexus I am observing frequent regular periodic polling by accounts-daemon on an idle system. Running strace on it I see:

poll([{fd=4, events=POLLIN}, {fd=7, events=POLLIN}], 2, 537) = 0 (Timeout)
clock_gettime(CLOCK_MONOTONIC, {12270, 5725668}) = 0
inotify_add_watch(7, "/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)
clock_gettime(CLOCK_MONOTONIC, {12270, 7373617}) = 0
poll([{fd=4, events=POLLIN}, {fd=7, events=POLLIN}], 2, 3993) = 0 (Timeout)
clock_gettime(CLOCK_MONOTONIC, {12274, 8106038}) = 0
inotify_add_watch(7, "/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)
clock_gettime(CLOCK_MONOTONIC, {12274, 9204671}) = 0
poll([{fd=4, events=POLLIN}, {fd=7, events=POLLIN}], 2, 3991) = 0 (Timeout)
clock_gettime(CLOCK_MONOTONIC, {12278, 6854036}) = 0
inotify_add_watch(7, "/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)
clock_gettime(CLOCK_MONOTONIC, {12278, 8318940}) = 0

So it is polling every 4 seconds and timing out. Is this polling absolutely necessary since it is essentially blocking on fd 4 and 7?

Also, it is interesting that every poll loop it adds an inotify_add_watch on /etc/gdm which does not exist on the phone images. It seems a little bit wasteful to keep on doing this every 4 seconds.
