title: MySQL set wait_timeout for specific user
body: <p>Is it possible to set the global <code>wait_timeout</code> for a particular user?</p>
  
  <p>For example user: <code>jack</code> has a timeout of 60s and <code>root</code> user has unlimited timeout?</p>
  
  <p><code>SET SESSION wait_timeout = X;</code> only affects the current session.</p>
  
  <p><code>SET GLOBAL wait_timeout = X;</code> affects everything.</p>
