At least two implementations of Lisp on time-sharing systems in which
the runtime was shared between different user processes (only one copy
on disk, only one copy in main memory) existed over ten years ago:
PDP-10 Maclisp running under the ITS time-sharing system on PDP-10's
and DecSystem-20's at MIT, and Multics Maclisp running under Multics
on Honeywell 6180's at several sites.  Both worked essentially like
Sun shared libraries.  Unfortunately, my knowledge about modern Lisp
implementations is less detailed.
