New issue 516 by hpsMo... at gmail.com: XMonad and xmobar wake up too often  
and are consuming more battery power
http://code.google.com/p/xmonad/issues/detail?id=516

What steps will reproduce the problem?
1. Start XMonad and/or xmobar
2. Check their wakeup frequency with powertop
3.

What is the expected output? What do you see instead?
About half year ago when I used XMonad for the first time the wakeup  
frequency was only 10 times per second, sometimes even less. Now it often  
gets to 100, especially in idle state.

What version of the product are you using? On what operating system?
Debian wheezy. XMonad 0.10-4+b2 from debian official repo.

Are you using an xmonad.hs?  Please attach it and the output of "xmonad
--recompile".
This issue is reproducible on my laptop with any configuration, including  
the default empty configuration.

Please provide any additional information below.
When there's an active X program running (like the chromium browser I'm  
typing in now), wakeup freq of both xmonad and xmobar are likely to drop to  
about 40/sec. But as keyboard and mouse become idle the freq rises up again.
