Now, we can, in principle, figure out which processes share code, and
we can glean dynamic library usage from things like lsof etc. Going
down that road seems a non-trivial project all by itself. My
question is, are there tools that do the job - or parts of it -
intelligently? The overall problem seems reasonable and practically
important, so maybe someone has solved it already. Any pointers and/or
fruitful ideas will be greatly appreciated.
Well, there is sort of a tool that does what you want. It's called the Linux Trace Tool Kit:

If you run it and confine that type of information traced to be limited to memory operation you might get some part of the answer. Writing some Lisp (for some value of Lisp) to analyze the logs produced yourself can give you the entire answer.
Here are a bunch of IBMers that contrinuted to this project which really knows about it a lot more then I do:
