    JONL says it's just soaking up free symbol space. It doesn't cost you
    anything. Seems pretty random, tho' ... I suppose when we need the
    symbol space for something else it will go away.
Files which are autoloaded can't guanantee sharing of the symbols, but
if some of these symbols are pre-existing from the initial lisp, then they
can just utilise the otherwise dead space in pure areas.  Doesn't cost
anything for the user who doesn't need the autoloading file, and saves 
space for the onewho does.  As KMP says, just which symbols "soak" up
this sp[ace is a floating decision.
