I was told that 503 meant server busy and that the client should continue
to retry after a slight delay until it could get through. Maybe I was
mis-informed? For now I will remove the retry behavior so that Netscape
fails gracefully when a 503 is encountered and not retry again. Whenever
someone finally figures out what to do in the 503 case I'll reimplement
the new solution.
