[Speed] Running pyperformance on Windows

[Victor Stinner]

Hi Peter,

Thank you for your bug report. The bug is a recent regression in the
perf module. I just fixed it with the newly released perf 0.9.3.
http://perf.readthedocs.io/en/latest/changelog.html#version-0-9-3-2017-01-16

I also released performance 0.5.1 which now uses perf 0.9.3. By the
way, I fixed perf and performance unit tests on Windows. Changes:

* Fix Windows support (upgrade perf from 0.9.0 to 0.9.3)
* Upgrade requirements:

  - Chameleon: 2.25 => 3.0
  - Django: 1.10.3 => 1.10.5
  - docutils: 0.12 => 0.13.1
  - dulwich: 0.15.0 => 0.16.3
  - mercurial: 4.0.0 => 4.0.2
  - perf: 0.9.0 => 0.9.3
  - psutil: 5.0.0 => 5.0.1
