Yes. All I'm saying here is that, if there's something
we can do to make it even better and it's a very small
mod, then we might as well feed it back into the kernel
source. But I agree, we should be able to run things
as well as possible without modification.
It might not even make a difference. If it does, maybe
we can get some bragging rights to our 4 lines of contribution
to the Linux kernel. :^)
