Reading procfs is a rather slow operation and sometimes when reading it in bulk you only need a specific file like /proc/<pid>/maps, which is currently constructed through Process.maps().

Is there a reason why the Process structure constructor reads and parses /proc/<pid>/stat by default? Also, recently it got coupled even more, see bfd2c86.

It would be nice to have bare Process structure and then query the related resources on an on-demand basis.
