so many applications wake up so often

Using strace, I discovered many programs are constantly busy these
days. No wonder one can't seem to save power. There ought to be a law...

...The OLPC/Fedora people are working on eliminating application
wakeups in order to save power. I cite here from one of the bug
reports about this:

   "We're working with RH engineers on a tickless idle kernel, which
   has the goal of reducing power and hypervisor loads when the system
   is idle. This is done by removing the regular ticking clock when
   the system is idle, so that in theory long sleep periods are
   possible for the hardware (or hypervisor). The kernel portion of
   this works great, however when using a gnome desktop there are many
   however when using a gnome desktop there are many timers going off
   all the time for userspace, so many that the actual savings are not
   so great (about 250 events per second)."

Given that so many applications wake up so often, what emacs does
might not be measurable at this point, but it might make a difference
in the future.
