/**
 * \fn vm_segment_grow
 * \brief Grow the size of the segment
 * \param s
 * \param size
 * \brief The size by which we want the segment to grow
 * \return A standard error code
 * By the way, notice how it is only possible to grow a segment?
 * Indeed that's by design. Segments can only grow, not shrink. If they could,
 * they might cut into allocated data, and that's bad. If pages aren't in use
 * anymore, paging should take care of those, so no need to worry about it here.
 *
 * \todo implement swapping and destroying of pages that have gone out of use.
