Just some housekeeping, but a display being disconnected is like a drawing halt, you can't do any opengl calls until it's handled. So you have:
gotDisconnectNotification() {
sendAllegroEvent(DISCONNECT);
waitForAcknowledge();
housekeeping();
}

No, it has to be handled. Right now it waits up to 5 seconds, after that it just goes on as if the user acknowledged. Which will mean a crash in most cases.
