The NVidia GL libraries are notorious for being linked with text relocations. 
Each program that so much as loads that libGL gets 10-15 MB more memory usage, 
from start.

NVidia knows about this and will not do anything. Enabling -fPIC does cause a 
performance regression because of indirect memory accesses and by reserving 
one register.

Simply adjust your expectations: anyone using NVidia proprietary drivers will 
have to deal with this issue. So discount the 10-15 MB increased memory usage 
per application using libGL and check your numbers again.
