Ask HN: When is there too much navigation?

Screen real estate is one of the top concerns for my personal computing setups. You've probably seen toolbar overload - http://bit.ly/w0xOEm - but what do you think about this: http://bit.ly/yfvRJV

That's 6 *-bars: os, environment, browser, site family (google), site, sitetools. After those, you finally get to content. No, we're not programmed to scan each pixel from top to bottom every time, but it seems like navigation should be more compact relative to the content.
