title: Terminal not responding in Cloud9 IDE Rails
body: <p>I'm working my way through the Ruby on Rails Tutorial, and suddenly the terminal is not responding to common commands.</p>
  
  <p>Entering commands like "bundle exec rake test" or "rails console" creates the situation in the screenshot below and waiting hours does not change anything.</p>

  <p>I can type on the line but the Terminal still doesn't respond to any commands here. Ctrl+C allows me to escape the previous request and get back to the command line.</p>
  
  <p>Strangely, "git status" works fine and quick.</p>
  
  <p>Any ideas how to fix this?</p>
  
  <p>I've tried restarting the Terminal and re-loading the workspace.</p>
