Did you see with any of the Owners if that is fine with them... I don't really
see why you are doing this. Can you use a  NetLogLogger as it is with a given
file path where you need it, instead of having all those static methods?

+  // Stop collecting NetLog data into a temporary file.
+  static void StopNetLog();
+
+  // Send NetLog data that is in the temporary file.
+  static void SendNetLog();
+
  private:

+  void OpenFile();

+  // Send NetLog via email.

1. attach
2. Why isn't this a const FilePath& ?

+
   ScopedStdioHandle file_;
+  FilePath log_path_;
+  std::vector<FilePath::StringType> files_to_delete_;

Same thing here, why isn't those FilePath?
