28 * mono_runtime_set_shutting_down:
30 * Invoked by System.Environment.Exit to flag that the runtime
33 * Deprecated. This function can break the shutdown sequence.

42 * mono_runtime_is_shutting_down:
44 * Returns whether the runtime has been flagged for shutdown.
46 * This is consumed by the P:System.Environment.HasShutdownStarted

85 * mono_runtime_try_shutdown:
87 * Try to initialize runtime shutdown.
89 * After this call completes the thread pool will stop accepting new jobs and no further threads will be created.
91 * Returns: TRUE if shutdown was initiated by this call or false is other thread beat this one.
