Remove posts file if it gets too large

If posts gets above a certain size, delete it.

This one should probably be more specific, how large is too large?
Also, how important is keeping very old posts notifications? What is the probability of accidentally posting to a month old thread if we're not keeping track of it?

/r/all/new is newest posts and every loop we only look at the most recent posts. We only ever pull from the last 20 submissions in /r/all/new and that's done once every 30 seconds.

We will never post a comment to a month old thread because of what I just explained. /r/all/new is posts in chronological order starting from the point in time that you loaded the page to the beginning of reddit.

In order to post to a month old thread we would have to increase the posts we are looping through up to the millions because reddit gets so many posts a month.
I think we should keep the most recent 1000 posts we processed. (Currently my posts file is over 34,000 posts processed and I clean it every week or so.)
