It's kind of an old-fashioned terminology in the lisp world for procedures that try to determine the parts of the lisp that are not used at runtime. In some languages that's simple: you just don't link things that are not referenced. In lisps it's not so cut and dried, because programs can dynamically construct references to things, thus the metaphor of "shaking loose" things that are not "strongly attached".
