Console app. that monitors posts won't close

[edhalsim]

I'm monitoring a subreddit using:
subreddit.Posts.GetNew();
subreddit.Posts.NewUpdated += NewPostsUpdated;
subreddit.Posts.MonitorNew();

        // Stop monitoring subreddit for new posts.
        subreddit.Posts.MonitorNew();
        subreddit.Posts.NewUpdated -= NewPostsUpdated;

I'm also monitoring scoring, e.g.:
post.MonitorPostScore(minScoreMonitoringThreshold: 1);
post.PostScoreUpdated += PostScoreUpdated;

All this works, but when the app. should close (all code in Main is complete), it just sits there. It won't stop the app. I tried disposing any current threads, but that didn't help. I also tried keeping a list of all posts that I added the event handler to and I removed that, still won't terminate. Suggestions? Thanks.
