So the fix is a bit more involved and there's already an enormous update to the osc block waiting to be merged, which I will put this change into as well. For now, if you just poll the io_service after a close and before you reset the pointer everything seems to work fine. Replace the above keyDown function with this...

void SimpleReceiverApp::keyDown( KeyEvent e )
{
    mReceiver->close();
    io_service().poll();
    mReceiver.reset();
    setup();
}

...and you should be good to go. I'll try and get everything merged in ASAP.
