I don't think you know how to accurately measure memory usage.

Try the following experiment:

* Kill Nautilus and all related processes

* run top, observe total free memory (and leave it up)

* Run Nautilus

* observe total free memory again

* compute the difference

I get about 12-14M total difference this way. The way you are using
gtop does not account properly for shared memory or parts of
executables or libraries that never page in, I believe.
