I don't want it to buy me anything since I don't think we need this
behaviour. I was just explaining it for someone else. :)

Actually, that may not be the case. Since they updated B they should have
rebuilt C (if not then we have a process break and there is nothing SVN can
do about that one). When I update I would get that older B but C should
conflict (it better but to be honest I'm not positive it would given SVN's
handling of binaries and my lack of SVN experience. anyone?). In this case
I will have to rebuild C to clear the conflict and everything will be good.
Of course if SVN merge's executable binaries then all bets are off....
