an idea of how sparse the sbitmaps are? If they are real sparse, it might be
useful to recode them to use bitmaps instead, adding appropriate macros if
needed to find the subset or to do 3 operand addressing.
As we use bitmaps more, we really should garbage collect these along with
everything else.
