No, the autotester does not run them _before_ a merge is done. It runs them 
_after_. So, it's quite good at telling you whether the code in master 
repositories for dmd, druntime, and Phobos is currently broken, but it doesn't 
tell you whether the code in _pull requests_ is broken, which appears to be 
what Walter is looking for. Daniel Murphy's autotester does that, but not the 
primary one - not unless you've changed something that I don't know about.
