It's basically the same as the L{take_memory_snapshot} method, but it
takes the snapshot of each memory region as it goes, as opposed to
taking the whole snapshot at once. This allows you to work with very
large snapshots without a significant performance penalty.

call the L{generate_memory_snapshot} method instead.
