For reference, folks, this is


Annoyingly, it's hard to grab a patch from a message body there, but
we should commit this, possibly with some tweaks:

For the BDB calls, we can't just rename "open" to something else,
since it's a name imposed by BDB. Joe's patch (wrapping the calls in
parens) is the right solution there.

For the Subversion vtables, we could just rename "open", and that
would probably be the more maintainable solution.

I don't have time to do this ATM, but I wanted to toss out these
