47 |  |
      * RunData is an interface to run-time information that is passed
48 |  |
      * within Turbine. This provides the threading mechanism for the
49 |  |
      * entire system because multiple requests can potentially come in
50 |  |
      * at the same time.  Thus, there is only one RunData implementation
51 |  |
      * for each request that is being serviced.
