Oh, thanks, now I understand! But the revisions are also immutable - isn't it simpler just to select maximum revision ID in the beginning of dump and just discard newer page and image revisions during dump generation?
Page history structure isn't quite immutable; revisions may be added or deleted, pages may be renamed, etc etc.

Shelling out to an external process means when that process dies due to a dead database connection etc, we can restart it cleanly.
