I'd recommend against that.  Apple recently changed OS X so that
it rejects SHMMAX settings that aren't an exact multiple of
something-or-other, and I've found that to be a *serious* PITA.
Of course part of the problem is that there's no helpful message,
but it's still a big loss from a usability standpoint, and quite
unnecessary (every other Unix seems willing to round off...)

One thought is that maybe we should round up not down?  I'm having
a hard time making a specific case either way, though.
