~RpcServer() calls shutdown explicitly.
If a thread is calling RpcServer::join() and poll()-ing,
when ~RpcServer() is called, the first thing it does
is deleting mJoinShutdownTrigger, which will close the
read end first.
poll(2):
For a discussion of what may happen if a file descriptor being
monitored by poll() is closed in another thread, see select(2).
select(2):
If a file descriptor being monitored by select() is closed in
another thread, the result is unspecified.
To avoid relying on UB, properly shut down before closing these fds.
