With Ruby's open classes, you shouldn't have to. At the top of your
file/library/program, just open the class you'd like to modify, in
this case the module Net and the class BufferedIO, and do what you
want.

Something like:
module Net
  class BufferedIO
    def rbuf_fill
      timeout(@read_timeout) {
        #changed by cburt to a much larger buffer for speed
        @rbuf << @io.sysread(16384)
      }
    end
  end
end

Note: Modifying the standard library is usually considered bad form,
but if you know what you're doing and are explicit about it it's
usually ok.


HTH,
