title: Change process priority in Python, cross-platform
body: <p>I've got a Python program that does time-consuming computations. Since it uses high CPU, and I want my system to remain responsive, I'd like the program to change its priority to below-normal.</p>
  
  <p>I found this:
  <a href="http://code.activestate.com/recipes/496767/" rel="noreferrer">Set Process Priority In Windows - ActiveState</a></p>
  
  <p>But I'm looking for a cross-platform solution.</p>
