not as it stands: the ss10 mmu.c is based on my mmu.c for the lx/classic,
which in turn was based on a mixture of the next and ss mmu.c files.
it lacks interlocks, at least.  a better approach on a multiprocessor might be to
adopt the strategy of power/mmu.c and chm/mmu.c: they use a stunningly elegant
distributed garbage collection algorithm (and very little code)
to manage a collection of virtual contexts across the TLBs of a multiprocessor.

HP had some jukeboxes that seemed promising (a reasonable amount of storage
without a huge price tag), but are probably still a little expensive for home use.
then again, if you're considering FDDI you might be able to afford them.
i've read that HP has pulled out of the disc business, but i'd be surprised if that
included WORMS.

you'll probably need to change the file server code slightly to support something
other than the Sonys.
