whee, I too have 128M at work and 256M at home! :)

Compared to Mozilla KDE is okay. However, I am a fan of projects like
dietlibc/uclibc, qmail etc... kernel also comes to mind.

For example, my KMail has only three windows open and it uses 16004K
for malloc() only:

0825c000    16004K rwxp [heap]
40cfb000     6180K r-xp /.share/usr/app/qt-x11-free-3.2.3/lib/libqt-mt.so.3.2.3
4062f000     2612K r-xp /.share/usr/app/kde-3.1.4/lib/libkio.so.4.1.0
40013000     2584K r-xp /.share/usr/app/kde-3.1.4/lib/libkhtml.so.4.1.0
408d5000     2092K r-xp /.share/usr/app/kde-3.1.4/lib/libkdeui.so.4.1.0
08048000     2040K r-xp /.share/usr/app/kde-3.1.4/bin/kmail
40b1c000     1412K r-xp /.share/usr/app/kde-3.1.4/lib/libkdecore.so.4.1.0
416b7000     1080K r-xp /app/glibc-2.3.2/lib/libc-2.3.2.so
41498000      752K r-xp /.share/usr/X11R6-4.4.0/lib/libX11.so.6.2
4049c000      744K r-xp /.share/usr/app/kde-3.1.4/lib/libkdenetwork.so.2.0.0
418e5000      740K r-xp /.share/usr/app/gcc-3.4.3/lib/libstdc++.so.6.0.3
41a0a000      640K rwxp [ anon ]

I think it is a bit too much of heap. I can be argued into agreeing that
libqt-mt.so.3.2.3 and friends are tolerable since these are shared among
processes, but heap is not.
