The issue with cursor is really disadvantage, I'll try to fix it
later.

Well, the "sort" operation is invasive, it changes mapping between
devname and the real area on the disk. I'd like to be careful with
this feature, but I think we can enable it for logical partitions if
we created all extended partition. Added to TODO.

This is makes sense only if you create all the logical partitions from
scratch, otherwise gaps between partitions are reality which should
not be hidden.
