Andrei Budnik commented on MESOS-8545:
--------------------------------------
`libprocess::finalize()` solves the problem, because it waits for termination
of all libprocess actors (including `HttpProxy`) in
`[ProcessManager::finalize()|https://github.com/apache/mesos/blob/12636838f78ad06b66466b3d2fa9c9db94ac70b2/3rdparty/libprocess/src/process.cpp#L2395-L2420]`.
This guarantees that all responses are sent back to the agent before
IOSwitchboard exits from its `main()` function.
> AgentAPIStreamingTest.AttachInputToNestedContainerSession is flaky.
