Indeed, nor do I.  Thought ecls did this, but their binary is not
dynamically linked against anything that looks like a lisp runtime.  I
do think they put the lisp runtime in a static lib.  My question is
that if it was shared, would it be effective, as the lisp heap would
change with use, and would duplicate the relevant pages in any
copy-on-write shared memory layout.

Yes.  Check out the tkl.o!  Of course, we're trying to make sure it
works in another thread :-).

Take care,
