Indeed. Really, for locking reasons, this is something that the API
should enforce. An editor should be uploading "I changed this node
from HERE to THERE" and if HERE is no longer true, the API should
reject the upload with a conflict resolution request (of some sort ...
details left for speculation by the reader).
(Maybe it already does this, and it isn't working properly for
Potlatch for some reason. I haven't looked at the source or the API
docs for confirmation.)
