                   9038: Do an ssi with retries:
                   9039: While I'd love to factor out this with the vesrion in lonprintout,
                   9040: 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
                   9041: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   9042: 
                   9043: At least the logic that drives this has been pulled out into loncommon.
                   9044: 
                   9045: 
                   9046: 
                   9047: ssi_with_retries - Does the server side include of a resource.
                   9048:                      if the ssi call returns an error we'll retry it up to
                   9049:                      the number of times requested by the caller.
                   9050:                      If we still have a proble, no text is appended to the
                   9051:                      output and we set some global variables.
                   9052:                      to indicate to the caller an SSI error occurred.  
                   9053:                      All of this is supposed to deal with the issues described
                   9054:                      in LonCAPA BZ 5631 see:

                   9057: 
                   9058: Parameters:
                   9059:   resource   - The resource to include.  This is passed directly, without
                   9060:                interpretation to lonnet::ssi.
                   9061:   form       - The form hash parameters that guide the interpretation of the resource
                   9062:                
                   9063:   retries    - Number of retries allowed before giving up completely.
                   9064: Returns:
                   9065:   On success, returns the rendered resource identified by the resource parameter.
                   9066: Side Effects:
                   9067:   The following global variables can be set:
                   9068:    ssi_error                - If an unrecoverable error occurred this becomes true.
                   9069:                               It is up to the caller to initialize this to false
                   9070:                               if desired.
                   9071:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   9072:                               of the resource that could not be rendered by the ssi
                   9073:                               call.
                   9074:    ssi_error_message   - The error string fetched from the ssi response
                   9075:                               in the event of an error.
