Interesting issues.  My experience using the system is that this isn't
much of a practical problem; the 'new version' is written out over a
tightly-clustered amount of time, and groups are easy to distinguish.
If you want a solid semantic solution to the problem, you're looking
at something like:

but that requires extending the filesystem API to support
transactions.  I love transactions, but I don't think they are
strictly necessary for us at this time.
