Only if it actually simplifies the VM and FS code noticeably.

Right now the VFS code already has all the complexity to handle
re-creating the buffer heads, so there's nothing to be gained from wasting
memory on them.

But we could make it an implementation decision to _always_ have the
buffer heads hanging around, and simplify (and possibly speed up) the code
by having that rule. It's not the case now, though.
