    No, the VM subsystem... that is, the concept of using stackable VM Objects, is going to stay in. I do want to implement a copy-on-write mechanism for pages owned by in-progress I/O to avoid stall situations that still exist in FreeBSD (despite Kirk's filesystem bitmap hacks, which only really fixed the worst of the stalls). There are also some kernel memory subsystem interactions with the VM system that need cleaning up to make things more MP friendly, and vm_map's and a few other areas need some algorithmic cleanups... but it's just cleaning up, not a rewrite. Generally I believe the VM Object based VM subsystem used in FreeBSD and DragonFly to be superior to the mechanisms used in other BSDs and in Linux.
