Subject: [PATCH] explicitly destroying io_serv at the end of shutdown

when the io_serv is stopped it may still own std::functions/lambdas that have captured data in them.  If this captured data relies on another system like a logging system, for instance, waiting for destructors to be called by the atexit call may result in them accessing a destroyed system.  By explicitly resetting the io_serve after shutdown we in turn release any resources it has while the systems are still alive and well
