4 KB kernel thread stack patch?

Does anyone know what happened to the patch to reduce kernel thread stack size from 2 pages (8 KB) to 1 page (4 KB)? The patch was highlighted here on LWN weeks ago, but I never found any more information about whether it was merged, required more work, or was too risky for Linux 2.6..??

Well, it's certainly risky for a production system - it is good mainly for development where you are trying to spot bits of code that hog the stack. I think Linus should merge it in 2.7.1, so that it can be made safe by 2.8/3.0.

I don't know what happened to the patch, by the way.
