Shared memory indicates things which are shared at a library linking 
level (e.g. libc is a shared object which both processes will share).

This has nothing to do with the copy-on-write memory which is shared. 
(I.e. your parent process loads the application, then calls fork - each 
process sees 'its own copy' of all the RAM, but only pages written to 
are copied - the rest remain "shared").
