--- Comment #289 from Joe Terwilliger jolyon@nixbox.com --- Thanks Sebastian for clearing that up! The situation regarding this fix has been puzzling many of us for some ~~time~~ years.
I honestly have no idea how the source patch for this was derived, I merely cleaned it up and made it workable on OSX. My comment was based on probably incorrect assumptions I came to whilst adjusting the parameters in final tests.
