Pretty easy (almost) with the new hashed inventory format.  We don't want
truly atomic behavior on the pristine cache, as that'd slow darcs down too
much (and I don't see any way of avoiding this slowdown, short of
implementing our own journalling filesystem, which would definitely be a
nice option, but not so easy).
