Why shouldn't it end up in the source tree ? It has nothing to do with
bloating the kernel. Au contraire. A Mach port removes stuff from the
kernel (and puts it in microkernel).

And generally, a Mach version would make it easier to get an initial port
of Linux running on more platforms.

Not much I guess. You can simplify lots of the driver functionality I
think, so that you can reduce most of the overhead to the overhead of
function calls.

According to OSF, it was not much slower than the direct one on a x86 PC.

And, I have kind of bought the idea of the microkernel / VM.
