+// char *buffer = new char[1024];
+// delete[] buffer;
+// }
+//
+// We have a local variable 'buffer' pointing to the heap allocated memory.
+// When deallocating the memory via delete[], that local variable still
+// points to the memory, which means we will create a DeadBlock for it and move
+// it over to that block, essentially duplicating the allocation. Moving
+// the data is also slow.
+//
+// However, when we actually try to access the allocation after it has been
+// freed, we need the block to still exist (alive or dead) so we can tell
+// that it's a dynamic allocation.
