First, System V release 2 and above have a general purpose shared
memory facility.  We use this in our fourth generation language 
interpreter to cache allow centralized access to pseudo-code.  Second
some version of 4.2BSD(sequent for example), have implement and mmap
call that allow you to map a file into your address space.  This
almost exactly mimics your system call.
