I'm not sure I understand your point. Considering:

# size libc.so.2.1
text    data    bss     dec     hex
339968  16384   48004   404356  62b84

I'd assume a worst case program would need all of libc. The approx
7.5Mb RSS seems quite steep (to say the least). 

What makes ps decide to include shared lib code in the RSS calculation?
(maybe RTFS ?) Would not it be fair to consider libc.so are shared burden
that is system wide desperately needed?

Maybe it's just me.. But please try to enlighten me.
