Francesco Romani has uploaded a new change for review.
Change subject: sampling: make TotalCpuSample a function
......................................................................
sampling: make TotalCpuSample a function
make the TotalCpuSample class a function, which
returns a CpuSample namedtuple. The surrounding
code doesn't need to change, and the module is
now a tiny bit shorter and simpler.
