It's better than nothing, but not nearly as good as one might have hoped. On my system, about 3.5MB of the shared memory is the text portion of libraries such as libperl.so and libc.so which you'd expect to be shared anyway, so really only about 20.5MB/46.5MB of Perl memory is shared for each slave.
