Ugh. Glad you found this. I meant to circle back to this, but forgot
about it. When I did this hack I Was worried about the case where getting
summaries is slow (because none are in cache) and a result the client times and
initiates a new operation (while threads for old operation are still churning).
I need a better solution.
