Well, it'd be interesting to see if MOO or LPC would actually be winners.

Lisp gets a bad rap here.  Just about every C app on the system gets to mmap
in libc.so, and from there it gets worse:

~ slothrop$ uname -a

KDE looks pretty svelte in comparison---the terminal only needs 4M of shared
libraries to come up.  I'm still trying to forget the project from a few
years ago that linked in truly massive piles of CORBA and auto-generated
libraries....
