This article explains the problem:

Accurate memory usage statistics using smaps are also being used in 
Unladen Swallow benchmarks: http://www.python.org/dev/peps/pep-3146/#memory-usage

From the first link: 

> The vmsize and total rss size are the statistics that everyone is used to. The rss size is split into 
> “private” and “shared”. The private rss is what could be best called the process' memory usage.

This could end up being confusing for people used to the 'standard' 
definitions of RSS, so we may wish to consider a separate attribute 
for 'private' vs 'shared' RSS so as not to confuse people when they compare our values to top/ps or other statistics.

Closing out as a duplicate because this is going to be addressed by new get_memory_maps() methods ( issue 260 ).
