Very wise words... even low-end laptops around here have 128 MB.

I don't know what the hell I wasn't running the other day, but now, on a
session with just { gnome-terminal, emacs, evolution, epiphany, gaim } I
get

	Private_dirty for file mappings: 25120 KB

which is pretty scary :)  I'll eat my words of .data and friends not
being significant [hmm, wonder how much of this is not .data but
relocations].

I'll put a table of the output in my activity log; the numbers are
interesting.  libcrypto from openssl is particularly fat; BenM mentioned
that on irc.
