The 'shared' field in /proc/meminfo (source for 'top' and 'free') has nothing to do with {SysV,POSIX} shared memory. The 'shared' field referred to memory that was used by more than one process (shared libraries, shared text segments etc). As I understand it, under 2.4 the 'shared' field is very expensive to calculate, so we don't--the zero value is there to avoid breaking programs that parse /proc/meminfo.
