title: Weird "jobs" behavior within zsh
body: <p>I am getting weird behavior with the <code>jobs</code>, <code>fg</code> and <code>bg</code> commands in my zsh shell. Here is an example (this happens for all commands, not just <code>python</code>):</p>
  
  <pre><code>$ python &amp;
  [1] 21214
  Python 2.7.8 (default, Oct 19 2014, 16:02:00)
  [GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.54)] on darwin
  Type "help", "copyright", "credits" or "license" for more information.
  [1]  + 21214 suspended (tty output)  python
  $ jobs
  [1]  + suspended (tty output)  python
  $ fg 1
  fg: job not found: 1
  $ bg 1
  bg: job not found: 1
  </code></pre>
  
  <p>I am using the standard oh-my-zsh installation on OS X.</p>
