In case of shared libraries, its correct. Only one copy of the shared
library code exists in the core at any time. But about apps, I am not
sure whether if all the instances of bash running on a box share the same
code "segment". If an app forks then yes, the children would share the
same code area, but I doubt if two unrelated instances of the same
executable share the same code area.
