-Z0. Access data structures with accessor macros, then turn the heapinfo
-Zinto several arrays for faster access on machines with addressing modes.
-ZAlso, this eventually raises the possibility of maintaining multiple
-Zheaps.
-Z1. Possible heuristic to catch multiple frees. Introduce an extra word
-Zof heapinfo that says whether the remaining info is for something
-Zbusy or something free. Then we can catch attempts to free already-free
-Zlarge blocks, as well as things not belonging to malloc at all. In the
-Zcase of a fragment, we can check if the fragment looks like it *already*
-Zbelongs to the fragment list, by comparing it with the "first" fragment
-Zof the block, or checking its "prev" pointer to see if it points into
-Zthe block. Then if it looks like it might we can exhaustively search
-Zthe block's free list to see if the fragment is there or not. Extending
-Zthe heapinfo structure would have the benefit of making it a power of
-Ztwo and thus making array indexing faster, perhaps. Suitably adapted,
-Zthis heuristic could also catch invalid pointers passed to realloc.
-Z
-ZAll of these additional features require the inclusion of <malloc.h>.
-Z3. indirect reference allocator: ialloc(), ifree(), irealloc().
-Z4. garbage collecting allocator: galloc(), garbage(), gfree(), grealloc().
