* (2014) In a [comment about memory_profiler](http://www.marinamele.com/7-tips-to-time-python-scripts-and-control-memory-and-cpu-usage), this person says 2 important things: (1) that memory_profiler is faster if psutil is installed, and (2) that measuring memory influences time. *Maybe tests that measure memory and cpu should be run separatelly from tests that measure time.*
