Subject: How to make common packages load only once?

I am using a common subset of packages (like :cl :cl-who :cl-
ppcre :flexi-streams :hunchentoot) among a few of my own asdf systems.
When I started to save images using sb-ext:save-lisp-and-die I found
that the size of the image doubles when add another package based on
the subset mentioned above. Does it mean that for every asdf system I
load into the lisp image the common packages are not shared between
all of them but duplicated? Is it possible to make them load once?
