Hi Eric,

Thanks for your very quick response!

Yes, it was the second patch that I saw as the most efficient way to 
deal with the problem.  I mentioned the first one because we were 
considering using deferrable timers until we saw your workqueue patch. ;)

Indeed, the interest seemed to have died out.  But I was not sure 
whether there had been some other discussions elsewhere and the decision 
had been not to take that patch because of some real technical reasons.  
I'm glad that was not the case ;)

I applied your patch on top of the 2.6.28 I'm using and will start 
testing it now.  I can also try to test it on top of 2.6.31-rc4 plus 
wireless-testing stuff, if needed.

I'll tell you that I liked your patch in a moment (I actually already 
liked it, but I'll wait until I know it works before I tell you ;)
