/*
Calculating a precise critical path, taking into account the deep dependeny structure, is non-obvious.
Dependencies have the type [{X}], e.g:

    X = [{a,b},{c,d}]

That is r builds a and b, then after those both complete (assuming they don't change), it builds c and d,
then it is finished. Importantly, r doesn't start building c/d until after a and b have finished. This
detail extends the critical path.

To calculate the precise critical path, we simulate with the notion of demand and waiting.
