Indeed.

for a better idea of how much memory is used, you should consider 
looking at PSS instead, which has a better correlation with actual 
memory used by the application. Here's what "memuse" (a Pss reading 
tool) says on my system with NVIDIA gfx:

    25648Kb		Thunar --sm-client-id 2a155738e-ac40-43c6-b930-d720415fbbac

note that the sizes are still considerable, and some of them are just 
plugins.
