+1 because you have to think about it again

I would be cool to have them all green soon on master:
for typo3:
 1616 tests, 2042 assertions, 52 failures, 107 skipped, 0 , 20 errors, 
20.441 seconds, 54 MB (56235176 B) memory leaks
for extbase, 2 failures (cli stuff)
fluid just fatals :( (@Process request sets widget configuration)
for index search 1 failure (Local path with abs ref prefix)
others are green

Lets go for green bar feeling!

Cheers
Phil
