One way of doing this is to use reference counting as usual, but in
addition you keep track of all allocated memory. Every once in a while
you run a mark&sweep GC in the traditional way, using your list of
allocated memory to identify unreferenced memory blocks, and
recalculating the reference counts as you trace the referenced blocks.


Other hybrids are possible and limited only by your imagination (and the
application's requirements).
