If you join the thread the exception will be re-thrown in the context of the joining thread. I've been considering changing the behavior to terminate the app if an Error is thrown in a thread, but so far have not done this because basically no cleanup would occur, unlike when an Error is thrown in the main thread. Alternately, I've considered having all app threads be actual threads so the main thread wouldn't get special treatment. If we move towards green-threading with std.concurrency this is basically what would be needed anyway, but I'm not sure it's appropriate as the default behavior for a systems language.
