+Subject: [PATCH] disable database flock timeout
+
+If there's another snapshotter instance running and that snapshotter
+has already acquired the file lock, we don't mind waiting indefinitely
+or until the other snapshotter dies. We don't want to fail because
+another snapshotter is already running.
