Is it too easy to accidentally overwrite another admin's changes?

[aslagle]

If two admins open a page in the admin interface and edit different parts of the same item, the second admin won't see the first admin's update after it's submitted. They will submit their edits with the old values for the fields the first admin changed, and may unintentionally revert the first admin's changes. Should the interface sync its data before submitting to detect this?
