I supplied a github branch with that patch. The view server was  
changed after I did it, which requires re-working the patch, and there  
were some other requests which I agreed to (slugs & slashes). The  
transaction issue is more important to me, so I'm waiting to see if I  
need to support a private branch for that before I revisit the unicode- 
file-name code.

When I posted the ruby indexer I noted that the full db-info is now  
provided per request - subsequent discussion prompted the db UUID  
thread idea. I haven't checked the code to determine the semantics of  
the purge_seq field - it may be enough to *catch* purges, although I  
think a purge hook would be a very useful optimization to ensure that  
externals don't require a full sweep.

I was providing a perspective for Martin Scholl, my point being that  
what he wants is doable now, without having to make the canonical  
store pluggable (which IMO is neither feasible nor desirable).

Even without DB uuids, external indexing is still a very useful model.

Yes, as I say, I supplied a gihub branch for using such modules. Even  
with no other changes, it's useful right now, and laughably trivial.

As far as core modularity is concerned, I don't know if it's feasible  
to patch that from outside the committers group because of the  
coordination required. I may be wrong.
