Description
The beast frontend handles pause_for_new_config() by calling boost::asio::tcp::acceptor::cancel(), which unblocks any threads that were only waiting on boost::asio::tcp::acceptor::async_accept().
However, existing keepalive connections will also be waiting to read the next message header with beast::http::async_read_some(), and that prevents boost::asio::io_service::run() from returning to complete the pause.
This means that keepalive connections will cause pause_for_new_config() to hang until all such connections are closed by the clients.
