 * restart while the other does a shutdown):  this class extends

 * <CODE>org.opends.server.core.DirectoryThread</CODE>, and this thread is not a
 * daemon thread.  These changes are needed to guarantee that the JVM does not
 * exit before we get a chance to restart it if all non-daemon threads go away.
