  Unix's pa did that, and it worked quite well:  the file system was
mostly managed by the VMM, and the code was smaller than a seperate
file system and VMM (is was larger than the v6 swapper & file system,
though).  It is also trivial to build a file-system-flavored interface
to a VMM-based disk system, which is what both Multics and presumably
Apollo did.
