What if the `download` function is somehow async recursive?

What this does depends on the details. Most likely your function would be like downloadList(list) that returns a promise resolving when everything is done. Then queue.wrap would limit simultaneous downloadList executions. If they internally make sequential downloads, this probably ends up doing what you wanted. If internally they start all downloads at the same time, you'd need to queue.wrap also the recursive call inside downloadList (ideally in a different queue, because the downloadList promise won't resolve until all is done).

Closing this for now. If you run into some scenario that causes problems, please post it here. I'll reopen the issue and try to fix it.

Now I probably understood your question. There's a new unblock method and a section in the readme about recursion:

Hopefully this answers your question.
