There is a library developed at CMU for Unix and Mach called RVM
(Recoverable Virtual Memory).  A similiar idea to Multics segments, it
is used in CMU's Coda filesystem (successor of AFS).

The Mach version (e.g. MkLinux, Hurd) uses external pagers for
customizability and to avoid I/O delay for mapping regions.
