I notice aaronl is picking fights with everyone who responded to his flamage, but clearly hasn't read my tips on accurate measurement of memory use, because he has neither pointed out where I'm wrong, nor retracted his misleading remarks.

"RSS" and "SIZE" are not remotely accurate measures of the actual memory load a program places on a system; they can either underestimate or overesitmate, for a huge variety of reasons, of which shared libraries are only one.
