I like it too!

But, we'll have to transmit the dirty bit to the server somehow. That
is, if you tell the server you have directory D at revision 9, and
then tell it you have the following children of D also at revision 9,
the server won't assume that any unmentioned children are deleted --
it will assume they're also at revision 9! :-) So state reports will
need to incorporate the dirty bit, probably not too difficult (?)...
