   =item * ssi_with_retries(resource, retries form)
   
   Performs an ssi with some number of retries.  Retries continue either
   until the result is ok or until the retry count supplied by the

   Inputs:

   retries    - Count of the number of retries allowed.
   form       - Hash that identifies the rendering options.
   
   Returns:
