Steele (p. 265-6) implies that DELETE-PACKAGE will not actually get
rid of the symbols in the package, just leave them in limbo. I want
to get rid of a package and its contents so thoroughly that they can
be garbage collected. How can I do this?

So you really mean that if you have some code in another package with
a reference to MY-DESTROYABLE-PACKAGE::FOO, you want it to suddenly have an
invalid referens? Or NIL, at best?

I only intended to use it to clear out EVERYTHING, so I could reload
all of my files with impunity.
(Someone has sent me code that looks like it will do the trick.)

There's no simple way to do this. As with any Lisp objects, they can only
be GC'ed when there's no possibility of accessing them.
For variable names, functions names, and quoted symbols referenced from
functions in other packages, you'll have to redefine or undefine those
functions. For symbols incorporated into data structures, you should clear
out those references. If the symbols have been imported into any other
packages you'll have to unintern them.
