                   9400: 
                   9401: Do an ssi with retries:
                   9402: While I'd love to factor out this with the vesrion in lonprintout,
                   9403: that would either require a data coupling between modules, which I refuse to perpetuate (there's quite enough of that already), or would require the invention of another infrastructure
                   9404: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9405: 
                   9406: At least the logic that drives this has been pulled out into loncommon.
                   9407: 
                   9408: 
                   9409: 
                   9410: ssi_with_retries - Does the server side include of a resource.
                   9411:                      if the ssi call returns an error we'll retry it up to
                   9412:                      the number of times requested by the caller.
                   9413:                      If we still have a proble, no text is appended to the
                   9414:                      output and we set some global variables.
                   9415:                      to indicate to the caller an SSI error occurred.  
                   9416:                      All of this is supposed to deal with the issues described
                   9417:                      in LonCAPA BZ 5631 see:
                   9418:                      http://bugs.lon-capa.org/show_bug.cgi?id=5631
                   9419:                      by informing the user that this happened.
                   9420: 
                   9421: Parameters:
                   9422:   resource   - The resource to include.  This is passed directly, without
                   9423:                interpretation to lonnet::ssi.
                   9424:   form       - The form hash parameters that guide the interpretation of the resource
                   9425:                
                   9426:   retries    - Number of retries allowed before giving up completely.
                   9427: Returns:
                   9428:   On success, returns the rendered resource identified by the resource parameter.
                   9429: Side Effects:
                   9430:   The following global variables can be set:
                   9431:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9432:                               It is up to the caller to initialize this to false
                   9433:                               if desired.
                   9434:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9435:                               of the resource that could not be rendered by the ssi
                   9436:                               call.
                   9437:    ssi_error_message   - The error string fetched from the ssi response
                   9438:                               in the event of an error.
