this doesnt work properly, also if you prevent a race with a mutex, the get_next_connection might wait without timeout and the a potential parallel shutdown signal can't simply close the socket, because under linux this doesnt wake the thread that currently blocks in accept. You need to use epoll and a eventfd. you register the listener socket and the eventfd at the epoll and wait on the epoll. shutdown then sends a message to the eventfd and wakes up the thread waiting for a connection. futhermore shutdown should marke the connectionacceptor as shutdown and prevent further waits. the socketlistener is then in the destructor destroyed
