title: Run my application in a simulated low memory, slow CPU environment
body: <p>I want to stress-test my application this way, because it seems to be failing in some very old client machines.</p>
  
  <p>At first I read a bit about QEmu and thought about hardware emulation, but it seems a long shot. I asked at <a href="https://superuser.com/questions/313374/full-hardware-emulation">superuser</a>, but didn't get much feedback (yet).</p>
  
  <p>So I'm turning to you guys... How do you this kind of testing?</p>
