Well, that sort-of worked. The '__db' files were recreated, then
subversion can read them, but the program ends with an 'Aborted' message
like so:

$ svn ls file:///path/to/svnrepo

Maybe this error is just a bug in the current code that will be fixed in
a day or two.

My Debian box has an NPTL based libc, so if the problem is
LinuxThreads/NPTL in origin I would think it would show up here as well.
A look at the 'changelog.Debian.gz' file shows that the libdb4.0
package has a "patch to allow db_recover to recover a wedged db_env".
I don't think this patch is in the remote machine's libdb, but that
machine may have other patches not on this machine.

Always doing an 'svnadmin recover' is a bit of a pain. More
investigation is required. The Berkeley DB libraries _are_ proving to be
quite a tricky lot to deal with ...
