The agent now reduces timeout for RPC requests. It doesn't affect existing requests, and so there is still an issue, but that should be (first) solved in oslo.messaging, for which bug 1672836 was reported. We may revisit how we interrupt RPC communication in the future when we have support for that in oslo. For now, let's close the bug.
