Since the GC keeps track of the length of the memory block, it can
also
tell whether the pointer is inside the memory block.
if (pointer >= startOfBlock && pointer < startOfBlock + blockLength)
doNotCollect();
How compute startOfBlock ? GC keep startOfBlock for each pointer
(pointer
consits of actual pointer and pointer to startOfBlock)?
or search for pointer such Block that pointer betwen
startOfBlock..startOfBlock + blockLength ?
The GC keeps a some sort of table of what it has allocated. IT can then just
look up all the startOfBlock/blockLength values.
