I don't understand: what's wrong with supporting lock timeouts as a
'core' locking feature in the libsvn_repos (or fs) libraries? As
ghudson suggested, the expiration time can be just another field in the
repository's representation of a lock. When some process -- whether it
be svnserve, apache, or ra_local -- tries to use the lock, or runs 'svn
update', or whatever, libsvn_repos code checks that the lock hasn't yet
expired. If it has, then it throws an error and/or tells the client
that the lock is defunct, and then deletes the lock object.

I don't think we need a special daemon hanging around, trying to delete
expired locks. Expired locks can be detected and tossed "lazily", only
when something lists or examines them.
