Big bag of pages
(BIBOP) Where data objects are tagged with some kind of
descriptor (giving their size or type for example) memory can
be saved by storing objects with the same descriptor in one
"page" of memory. The most significant bits of an object's
address are used as the BIBOP page number. This is looked up
in a BIBOP table to find the descriptor for all objects in
that page.
This idea is similar to the "zones" used in some Lisp systems (e.g. LeLisp).
