 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.
