"Some random dbm" won't work over NFS or another remote filesystem.
mod_dav_svn does not keep its activity db inside the repository.

It's possible, and relatively straightforward, to make the locking table
work using just the regular old filesystem. Just create a skeleton
directory tree mirroring the part of the repository which has active
locks. Store lock tokens at the leaves. URL-encode pathnames so that
encoding issues don't come into play.
