We wrote a small module and a user level program, which allows you to
merge memory of running processes. This is of course only working
for running instances of the same program.
You can see this as the inverse "copy on write" mechanism.
Maybe it can save you thousands of dollars for ram-upgrade for
your application server.

You are running sixtus prolog ?
