psutil, expect and setlocale

[jayvdb]

I am packaging this for openSUSE, and noticed that it was using ps. I noticed because that isnt in the standard rpmbuild image, so I got file not found errors in the execs. I wonder if it would be possible to use the Python package psutil instead, as that would make the tests a bit more independent of the host environment.

Also it is using expect. pexpect is another alternative.

Then this package can declare all of its test dependencies, and packagers will have an effortless time ;-)

Then the remaining problem I am facing is the test suite uses setlocale, which isnt working in an rpmbuild environment, causing the tests to fail like this:

   30s] > sh: warning: setlocale: LC_ALL: cannot change locale (en_US.ascii)
[   30s] 81a88

Feel free to open a PR if it fixes it :) would love to have less of a dependency on running commands such as that.
