I don't think there are any collisions, it's just that Vitja is currently 
removing the old visitor based attempts of doing variable initialisation 
analysis. Getting yet another one in while getting rid of the old ones is a 
rather unnecessary duplication of effort.

I suggest we rebase Vitja's branch when the current test issues are solved, 
then we'll see if there are any issues with the parallel looping code. I'm 
in favour of merging the control flow branch ASAP, simply because it's such 
a great feature.

I already disabled two tests in Mark's code that relied on uninitialised 
variables being None. There are likely others (way older ones) that were 
written with such misfeatures in mind.
