+ * pthread_kill() - we do not use this in LibVLC but some pthread
+ * implementations use them internally. You should really use conditions
+ * for thread synchronization anyway.
+ *
+ * Signal that request a clean shutdown, and force an unclean shutdown
+ * if they are triggered again 2+ seconds later.
+ * We have to handle SIGTERM cleanly because of daemon mode.
