    <note type="warning"><title>Warnung</title>
      <p>Dieses MPM ist noch experimentell und funktioniert m&ouml;glicherweise
        nicht wie erwartet.</p>
    </note>
    
    <p>Dies ist eine experimentelle Variante des Standard-MPMs
      <module>worker</module>. Das Modul verwendet ein 
      Leader/Followers-Design-Pattern, um die Arbeit zwischen Threads zu
      koordinieren. Weitere Informationen finden Sie unter <a
      href="http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf"
      >http://deuce.doc.wustl.edu/doc/pspdfs/lf.pdf</a>.</p>

    <p>Um bei der Erstellung  des <program>httpd</program> das MPM
      <module>leader</module> zu verwenden, f&uuml;gen Sie den Argumenten
      des <program>configure</program>-Skripts <code>--with-mpm=leader</code>
      hinzu.</p>
  
    <p>Dieses MPM baut auf den atomaren APR-Vergleichs- und -Tauschoperationen
      f&uuml;r die Thread-Synchronisation auf. Wenn Sie f&uuml;r einen
      x86-Rechner kompilieren, ohne dass 386-Unterst&uuml;tzung ben&ouml;tigt
      wird, oder wenn Sie f&uuml;r einen SPARC-Rechner kompilieren und keine
      pre-UltraSPARC-Chips betreiben m&uuml;ssen, f&uuml;gen Sie den Argumenten
      des <program>configure</program>-Skripts
      <code>--enable-nonportable-atomics=yes</code> hinzu. Dies veranlasst die
      APR veranlasst dazu, atomare Operationen einzusetzen, welche effizienten
      Befehlscode verwenden, der &auml;lteren CPUs nicht zur Verf&uuml;gung
      stehen.</p>
