but he's not asking for reserved checkouts, he's just asking for some
model where the client already knows what files you are editing, so it
doesn't have to stat everything to check when you want to diff or
commit or whatever.

this information /might/ be kept server side (like in perforce), but
that doesn't mean that the fact that i'm editing a file means nobody
else can. knowledge of what i'm working on != locks.
