I can think of three possible reasons:-
* Top is reporting it wrong.  Top is notoriously inaccurate for
programs that use a lot of libraries.  In some circumstances it just
does program_space + library_space.  Check how much memory a simple
GTK+ app appears to be using, if it says ~100MB then that's the problem
* GTK+ another fairly notorious bit of software.  AFAIK It can consume
a lot of memory if used in ways the authors were not expecting.  Maybe
try the Xaw version?
* CEDET.  Maybe there is a strange interaction between new Emacs and
CEDET?  CEDET also uses a lot of memory, but it shouldn't use this much.
