                   10942: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   10943:

                   10949:                      if the ssi call returns an error we'll retry it up to
                   10950:                      the number of times requested by the caller.
1.596.2.12.2.  8(raebur 10951:4):                      If we still have a problem, no text is appended to the

                   10965: Returns:

                   10974:                               call.
