title: Gevent multicore usage
body: <p>I'm just started with python gevent and I was wondering about the cpu / mulitcore usage of the library.</p>
  
  <p>Trying some examples doing many requests via the monkeypatched urllib I noticed, that they were running just on one core using 99% load.</p>
  
  <p>How can I use all cores with gevent using python?
  Is there best practice? Or are there any side-effects using multiple processes and gevent?</p>
  
  <p>BR
