I certainly hope so. The amount of memory used is ridiculous now.

This looks nice. I think it is better to use the offset pointer unconditionally
to see it works even in cases where we don't really need them.

Also, is there something like shared offset pointer? I don't know if it might be
useful or not, though.

However, I think there still be some difficulties. We may want to have multiple
segments allocated and point from one to another, for example.
