Sandeep Patil c6497eb1dc libmeminfo: defer maps reading only when required for procmeminfo ... This restores the original behavior. The main reason it should be this way is to make the class generic for all things memory under /proc/<pid>/. For example, with the current behavior, a program that only needs to read /proc/<pid>/smaps_rollup will end up wasting time and memory by parsing /proc/<pid>/maps when the object is being constructed. Same goes for a program that only wants to reset the working set. The 'ProcMemInfo' object still retains the property that it can only be used once to read maps and the object must be destroyed + recreated to update the stats.
