We discussed this quite a while ago, and I'm still not convinced that this approach makes sense. Can you give just one example of a use case where dirtying the whole bitmap while loading a snapshot is the desired behaviour? I think the most useful behaviour would be something where the bitmaps themselves are snapshotted, too. But for the time being, the easiest and safest solution might just be to error out in any snapshot operations if any bitmaps are in use. Kevin
