> There is some unwanted/unrelated recursion happening when Controller.install() is used recurisvely.
> Imagine there are 3 contexts A,B,C all waiting on dependency D
> When D is satisified all A,B,C do a further installation to the Controller.
> What happens is that Controller says A, B and C are resolved
> The controller then adds A to its "processing" set.
> When A does its install its spots B and C are ready to move
> and so it repeats the above for B which will in turn lead to the same thing for C.
> D installed -> A.start() -> install() -> B.start() -> install() -> C.start()
> When there are many A, B, C this will lead to a stack overflow.
> The A, B, C are actually independent so there it should look more like:
> D installed
> -> A.start() -> install()
> -> B.start() -> install()
> -> C.start() -> install()
> i.e. the invocations on A, B and C should happen on the same level of the call stack.
