   * This check is added to deal with Promise microtask queues. On the main
   * thread, we do not impose restrictions about when script stops running or
   * when runnables can no longer be dispatched to the main thread. This means
   * it is possible for a Promise chain to keep resolving an infinite chain of
   * promises, preventing the browser from shutting down. See Bug 1058695. To
   * prevent this, the nsGlobalWindow subclass sets this flag when it is
   * closed. The Promise implementation checks this and prohibits new runnables
   * from being dispatched.
   * We pair this with checks during processing the promise microtask queue
   * that pops up the slow script dialog when the Promise queue is preventing
   * a window from going away.
