It does. The library isn't copied to the memory space of the process.
Instead, it's "mapped" into the process. If you overwrite the file, the
old library is wiped from the system (disk and ram) completely.

Try this instead:

$ mv /home/nxuser/pp/lib/libstack.so /home/nxuser/pp/lib/libstack.so.old
$ cp libstack.so /home/nxuser/pp/lib/libstack.so
$ rm /home/nxuser/pp/lib/libstack.so.old

Or use the "install" command.
