I've never really understood recover's locking. Are there systems
where it is possible for a process to crash and leave a lock? On a
Unix like system the fcntl documentation usually states that locks are
removed when a process terminates.

svn_repos_recover has some odd looking code that opens the lock file
read-only and then unlocks the file. Does this ever have any effect?
Is it really possible for one process to release locks held by another
process?
