   Here I've specified a `:memory_max` option to the `keepalive` command. Now if
   the process memory usage goes above 150 megabytes, god will restart it.
  -Similarly, by setting the `:cpu_max`, god will restart my process if it's CPU
  +Similarly, by setting the `:cpu_max`, god will restart my process if its CPU
   usage goes over 50%. By default these properties will be checked every 30
   seconds and will be acted upon if there is an overage for three out of any
   five checks. This prevents the process from getting restarted for temporary

  Ctrl-C out of the foregrounded god instance. Notice that your current `simple`
  server will continue to run. Start god again with the same command from
  before. Now instead of starting the `simple` process, it will notice that one
  is already running and simply switch to the `up` state.
  
  ```terminal

  exits. For those systems without process event support, god will use a polling
  mechanism. The output you see throughout this section will show both ways.
  
  After starting god, you should see some output like the following:
