Nor is it particularly desirable. One of the cornerstones of how a modern generational GC performs as well as it does is that blocks of objects are freed up all at once. If they were deallocated in a piecemeal fashion then: - Freeing up memory would take longer, because you can't just change a pointer back to the root of the generation. - Allocating memory would take longer, because it involves searching for a big enough empty slot rather than just throwing the new object on top of the heap. - More memory is wasted overall, because of heap fragmentation.
