-       we do the following:
-
-       - For all paths still to be processed (‘todo’), we add all
-         paths for which we need info to the set ‘query’.  For an
-         unbuilt derivation this is the output paths; otherwise, it's
-         the path itself.
-
-       - We get info about all paths in ‘query’ in parallel.
-
-       - We process the results and add new items to ‘todo’ if
-         necessary.  E.g. if a path is substitutable, then we need to
-         get info on its references.
-
-       - Repeat until ‘todo’ is empty.
