unfortunately, deque::erase is O(n). Can you do something similar to
RemovePendingWritesForStream where you keep track of *out_it and then delete
everything after that? May want to copy that loop above and replace the
conditional. I don't know if it's worth decomping out into a helper method.

Done.
