        <para>Bdb will complain 'No locks available' when crawler is being
        built/run on an NFS mount. Workaround is not run on an NFS-mounted
        volume.

        <title>Postselector</title>
        <para>The Postselector has been refactored out of existence. 
        Its responsibilities have been parcelled out to two new Processors:
        LinksScoper and FrontierScheduler. LinksScoper is responsible for
        scope checking of extracted links. FrontierScheduler does the
        scheduling of URIs with the Frontier.
        </para>
        <para>This change was done to allow introduction of processors
        between scope checking and Frontier scheduling steps.
        </para>
        <para>Because of this change, order files from 1.4.0 Heritrix or
        before will need to be updated -- Postselector references replaced
        by LinkScoper and FrontierScheduler references  -- before they
        can be used with Heritrix 1.6.0 (Referencing a non-existent
        Postselector in an order file usually shows as -50 fetch status
        in crawl.log).
