This looks great, thanks Branko!

I'm now able to run 'make FS_TYPE=bdb svncheck' on my linux box with a
forking svnserve and there are no longer any failures. I know Branko
has some more work he's hoping to do here with regard to error
handling (see the comment about another potential pool destruction
ordering issue), but either way, this seems like an improvement, and I
think it should get merged into 1.4.x ASAP.

If more fixes to this are going to happen in the next day or so, then
we should probably hold off on a new RC, but if not, then I'd say we
should cut a new RC with this fix in it, since clearly the RC1 tarball
is rapidly becoming out of date.
