44 |  |
      * RunData is an interface to run-time information that is passed
45 |  |
      * within Turbine. This provides the threading mechanism for the
46 |  |
      * entire system because multiple requests can potentially come in
47 |  |
      * at the same time.  Thus, there is only one RunData instance
48 |  |
      * for each request that is being serviced.
