Strictly speaking, os.system is *not* deprecated in either Python 2.x or
3.x.

Latest stable documentation for Python 2.7 and 3.2:
http://docs.python.org/library/os.html#os.system
http://docs.python.org/py3k/library/os.html#os.system

And docs in development for 3.3 (unstable):
http://docs.python.org/dev/library/os.html#os.system

Deprecation means that there are active plans to remove the feature. There
are no such plans to remove os.system. What the docs say is much milder:

"The subprocess module provides more powerful facilities for spawning new
processes and retrieving their results; using that module is preferable to
using this function."

Using subprocess may be recommended, but that is not the same as saying that
os.system is deprecated. os.system will not be going away any time in the
foreseeable future.
