MFS has never done so.  MFS is simply a UFS which uses (swap-backed)
memory instead of a physical disk; it relies on the filesystem to
avoid touching blocks that it doesn't need, and on the VM system to
avoid wasting memory on allocated-but-untouched address space.
Historically, MFS would waste time copying disk blocks twice on their
way to the user, but I think this may have been fixed by Matt Dillon.
