Tru64 (from HewPaq) has a so_locations file in /usr/shlib containing
prelinked addresses for all the shared libraries in that directory.
If the library can be loaded at the prelinked address, it is, but it
will load elsewhere if necessary.

Of course, having 64-bit addressing helps reduce problems with
multiple libraries needing to use the same space.

This file is updated when you link a new shared library.
