1. Start a WebKit command prompt. https://docs.webkit.org/Ports/WindowsPort.html
2. Open Task Manager. Open the detail view. Select the 'cmd' or 'powershell' process
3. Change CPU affinity of the process to a single CPU
4. Run layout test in the WebKit command prompt
  python ./Tools/Scripts/run-webkit-tests --debug --force --iter=10 fast/workers/pending-requestAnimationFrame-upon-destruction.html
