title: OSX terminal running slow in git repositories
body: <p>I've noticed that whenever I type a command within a local git repository it takes around 7-8 seconds to register keystrokes and another 7-8 seconds to begin running the command. I've checked my logs from other apps like anti-virus software and haven't found anything obscenely large. I use iTerm, but I've also checked that the exact same thing happens when using Terminal. </p>
  
  <p>Any ideas on what the problem could be? </p>
  
  <p>If it helps, I'm on OSX Yosemite.</p>
