[xmonad] Another data point on delays in focus update.

[Allen S. Rout]

A month or so ago, I posted about some slow focus updates I was seeing 
in xmonad.

http://article.gmane.org/gmane.comp.lang.haskell.xmonad/12074

I noticed another correlation when this is happening, and thought I'd 
jot it down in this forum, in the hopes that it eventually contributes 
to a solution.

During the period when the focus is slowly traversing a lot of 
intervening windows, I've found that I peg a CPU running the X server; 
My Xorg process goes to 99%CPU and stays there for the entirety of the 
delay.

I've been watching the X cpu behavior because I've also noticed that 
some Firefox browser behavior will similarly peg the Xorg process for 
seconds at a time, and I was trying to suss that out.



I'm kind of free-associating here, but I'm wondering if xmonad's use of 
X resources is leaving Xorg with a long list of [wumpus]  that the X 
server can't collect or collapse or something,  I have no idea what the 
wumpus might be, but...
