Didn't see this get answered...  The long-and-short of that there aren't
any negative consequences of having it higher, as I understand it
anyway, except the risk of greedy apps.  In some cases, shared memory
can't be swapped out, which makes it a bit more risky than 'regular'
memory getting sucked up by some app.
