---- Having Google +1 button on a page will override robots.txt blocks!

i presume that google would crawl those URLs, rather than the ones that we are all worrying about.
My concern is that robots.txt has to be ignored to crawl these pages which means Google is disobeying and ignoring robots.txt... that should NOT be the default behavior though I suppose they want all the help they can get for +1.
I tried +1 but it yielded zero benefit for me and hurt page load times considerably, it wasn't for me.
