    Unfortunately, we need to delay a little bit... I am not a fan of it either. However,
I rebase this PR multiple times and it was never an issue on Travis (according test stability).
If you don't have strong objection against it, I would leave it. (The main cause of the problem
comes from Storm behavior we mimic here. `killTopology(...)` does not block in Storm, so we
do not block here either.)
