http://www.bughost.org/pipermail/power/2008-January/001234.html notes that syndaemon wakes up every 20ms (50 times a second!) to see if it's idle timer (nominally 2.0 seconds) has expired yet. That's a little much. I'd like to apply the patch noted in the URL above (which opensuse is carrying), plus a patch to make it poll every 200ms, dropping the wakeups to 5/sec. Objections? Patches inline below.
