Imagine you remove all IPC from the kernel. How do you send a user-space
message to another process? You can't.
That said, there is a lot of things in GNU Mach that can be in user space.
Mach is a microkernel of the first generation. Try to take a look at L4,
which is a modern microkernel that is extremely minimal.
Thanks,
Marcus
