Nope. Applications know how much the are sharing because they can
easily see what region of memory is shared/mapped into their's.
The reason the kernel can't figure out the net shared memory is because
there is no simple way -- it has to add up the shared regions of all
applications, counting each shared segment only once. Too much work.
