A POSIX/BSD superset.

Filesystems are implemented as translators and translators are user
level programs, so a filesystem could be implemented given an existing
Lisp implementation.  Besides being nice because one could use Lisp,
this would probably be useful for a hybrid Lisp/Unix environment
where, say, a subdirectory of files would represent the keys in a hash
table.

Also, the Lisp implementation could install its own pager to optimize GC
performance (not swapping out unused bits), or to create a persistent
store.
