CooperativelyShutdown(self, proc, app_name)
  `Cooperatively shut down the given process from subprocess.Popen.
  Currently this is only implemented on Windows. See
  crbug.com/424024 for background on why it was added.
  Args:
  proc: a process object returned from subprocess.Popen.
  app_name: on Windows, is the prefix of the application's window
  class name that should be searched for. This helps ensure
  that only the application's windows are closed.
  Returns True if it is believed the attempt succeeded.`

  On systems with multiple CPUs, this function may run on any CPU.
  Args:
  msr_number: The number of the register to read.
  start: The least significant bit to read, zero-indexed.
  (Said another way, the number of bits to right-shift the MSR value.)
  length: The number of bits to read. MSRs are 64 bits, even on 32-bit CPUs.`
