/* Getting substitute info has high latency when using the binary
cache substituter. Thus it's essential to do substitute
queries in parallel as much as possible. To accomplish this
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.
