   8  * This class has one method IsAlive() which can be called in either the
   9  * client or the server.
  10  *
  11  * client:
  12  *         KeepAlive is subclassed and an implementation of IsAlive() is
  13  *         written that checks to see if the server request should be
  14  *         terminated or not.  Note, this feature can be programmed using
  15  *         the API but must be instantiated using SetBreak() after the call
  16  *         to client.Init().
  17  *
  18  * server:
  19  *         The server has a couple of places where long running queries can
  20  *         stop and check to see if the client is still waiting (i.e. has not
  21  *         been terminated).
