OK, that's a great observation, and probably fixable. What were the 
author's comments when you told him that?

It's *very* late in the day to be ripping out such chunks of code.
1. Prove new code works better for you => make it a config option.
2. Prove new code works better for everyone => rip it out.

I think we're at 1, not 2.

Note that the userspace stuff doesn't even require that the kernel
stuff be disabled ... it should just override it (I can believe
there maybe is a bug that needs fixing, but it works by design).
