                   11207: 
                   11208: Do an ssi with retries:
                   11209: While I'd love to factor out this with the vesrion in lonprintout,
                   11210: 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
                   11211: I'm not quite ready to invent (e.g. an ssi_with_retry object).
                   11212: 
                   11213: At least the logic that drives this has been pulled out into loncommon.
                   11214:

                   11217: ssi_with_retries - Does the server side include of a resource.
                   11218:                      if the ssi call returns an error we'll retry it up to
                   11219:                      the number of times requested by the caller.
1.596.2.12.2.  8(raebur 11220:4):                      If we still have a problem, no text is appended to the
1.531     jms      11221:                      output and we set some global variables.
                   11222:                      to indicate to the caller an SSI error occurred.  
                   11223:                      All of this is supposed to deal with the issues described

                   11231:   form       - The form hash parameters that guide the interpretation of the resource
                   11232:                
                   11233:   retries    - Number of retries allowed before giving up completely.
                   11234: Returns:
                   11235:   On success, returns the rendered resource identified by the resource parameter.

                   11239:                               It is up to the caller to initialize this to false
                   11240:                               if desired.
                   11241:    ssi_error_resource  - If an unrecoverable error occurred, this is the value
                   11242:                               of the resource that could not be rendered by the ssi
                   11243:                               call.
                   11244:    ssi_error_message   - The error string fetched from the ssi response
