The thing is, we won't get Oracle to rewrite a lot for a completely
threaded system. And clone does _not_ come with a way to share only parts
of the VM, and never will - that's fundamentally against the way "struct
mm_struct" works.

Oracle is apparently already used to magic shmem-like things, so doing
that is probably acceptable to them.
