> It is possible that closing a listener while an incoming connection is about to trigger
an epoll event on the listener can result in accessing free'd memory.
> The solution is to force an event event to fire via a shutdown() call on the socket and
delay deletion until the callback completes.  This strategy is already in use by the pconnection
cleanup logic, which can be used as a template.
