public static void runInGossipStageBlocking(Runnable runnable) {
    // run immediately if we're already in the gossip stage
    if (isInGossipStage()) {
        runnable.run();
        return;
    }
    FutureTask<?> task = new FutureTask<>(runnable);
    Stage.GOSSIP.execute(task);
    try {
        task.get();
    } catch (InterruptedException e) {
        throw new UncheckedInterruptedException(e);
    } catch (ExecutionException e) {
        throw new AssertionError(e);
