title: Can I get the Ruby on Rails console to remember my command history, umm, better?
body: <p>I'm using the console in Ruby on Rails 3.1.1, and I'm finding its command history (up arrow) to be really flaky. I've run the commands <code>p = Product.by_name 'Acme'</code> and <code>p.add_search_term('Snipe')</code> several times today, across several console sessions. </p>
  
  <p>Yet, when I reload the Ruby on Rails console, only the first one shows in my command history, not the second. Sometimes they are both there in the history after I reload the console. On top of that, I see commands in my history that are from several days ago after pressing up arrow only a few times. Is there some sort of configuration that I need to change or is this a bug? </p>
