I endorse Guy Harris' posting. In addition to his remarks, note the following:

In most cases programs written in an interpreted language (LISP, PROLOG, even
BASIC) can be modified by the user from within sort of a toplevel. Shared
files are ok as long as users do not modify their contents! It is the same
with UNIX' shared images: only the text portions are shared among processes,
data areas reside in a process-private space. I think, however memory mapping
of files is a good idea, anyway, if used with large (read-only) data files
accessed by several users (e.g. font descriptor files).
