A thought ...
Shared libraries do 2 possibly useful things:
1) save space
2) stop you having to re-link when a new library is released.
Now 2) doesn't really happen anyway, due to .so versioning hell,
so we're left with 1) ...
I know it's kind-of hacky and unstructured (how do you know the venti
block size?),
but could you not block-align the library members in the .a,
so venti would do the sharing on disk for you?
Look at this:

As a further step, you could also page align the text segments of the
library members,
then implement a venti-like scheme for read-only pages in memory,
so that when the executable loads, it gets any common library pages
shared.

P.S. Sorry not to make Volos: where are the rest of the photos?
