Hmm, how about traversing from all the start commits downwards simultaneously, noting which start you say each commit from, and stopping when you have a commit carrying all start labels? I don't quite see how the same size plus lockstep works out (but the 'same size' part is possibly the same as my 'concurrent traversal'). > But didn't git forego the "single root" requirement in its commit DAG at > some point of time?
