I should've been more clear about that. I mean 'interfere' as in it raises
the current bar for potential conflicts with locking, deltification by
multiple processes, and for potential errors/problems that the user has to
deal with. I'd hate to see anything that would push back more problems to a
user. I.e., an increased potential for typical repository operations to

I wasn't sure how you were proposing this, and from some of the communication,
I was frightened that we'd essentially have to take the repository offline in
order to run this deltification process. However, if the current set up can
handle it, and the only difference is that we have to call 'svnadmin tunefs'
to do the deltification, then I'm alright with that (not that my opinion
counts for anything :-), especially if it enhances the user experience.
