Gregory Szorc 9ebe70267b Bug 930808 - Upgrade to psutil 2.1.3; r=glandium
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.

Summary
=======

psutil (python system and process utilities) is a cross-platform library for
retrieving information on **running processes** and **system utilization**
(CPU, memory, disks, network) in Python. It is useful mainly for **system
monitoring**, **profiling and limiting process resources** and **management of
running processes**. It implements many functionalities offered by command line
tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice,
ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports
**Linux, Windows, OSX, FreeBSD** and **Sun Solaris**, both **32-bit** and
**64-bit** architectures, with Python versions from **2.4 to 3.4**. PyPy is
also known to work.

A lot of time and effort went into making psutil as it is right now.
If you feel psutil is useful to you or your business and want to support its future development please consider donating me (`Giampaolo Rodola' <http://grodola.blogspot.com/p/about.html>`_) some money.
I only ask for a small donation, but of course I appreciate any amount.
