psutil 2.1.3 is replacing psutil 1.0.1. There are numerous bug fixes and feature enhancements in psutil worth obtaining. Source code was obtained from https://pypi.python.org/packages/source/p/psutil/psutil-2.1.3.tar.gz and uncompressed into python/psutil without modification except for the removal of the egg-info directory and the .travis.yml file. --HG-- extra : source : 697eb6db7d96dc21e817cd27a7e46ed4ab00f9bb
