+Bugfix: Improve error handling of repository locking
+
+When the lock refresh failed to delete the old lock file, it forgot about the
+newly created one. Instead it continued trying to delete the old (usually no
+longer existing) lock file and thus over time lots of lock files accumulated.
+This has been fixed.
