Darren, You are correct that interactive mode does have two effects, and I was only describing one--whether show blocks. The other effect of interactive mode is that pyplot commands, which include draw_if_interactive() calls, draw immediately when in interactive mode but draw only upon execution of show() when in non-interactive mode.
