  /**
   * The {@link org.openqa.selenium.grid.distributor.Distributor} is responsible for assigning new
   * calls to Create Session to a {@link org.openqa.selenium.grid.node.Node}. It's possible that the
   * first attempt to create a session fails for any number of reasons, and so a well-behaved
   * implementation will continue trying additional nodes until either a session starts or nothing is
   * successful.
   *
   * <p>To complicate matters, local ends may send a session request that is one of two different
   * dialects (presumably in the future there may be more. *sigh*) and care must be taken to ensure
   * that dialects match, or that a converter of some sort is added. The Node may be the part of the
   * system responsible for adding this converter.
