Does he really care? His view is at <c> and it's descendents. Now the
guy who takes <b>, his view is at <b> and it's descendents. He doesn't
want that view to change which means he'd have to have a lock on <b>
and all of it's descendents which includes <c>. However this is
starting to get into a lot of overhead and in most situations is not
needed. But if anyone is bored?

Agreed, to many issues.
