I need to update this description, but the kerneldoc comments are up to
date.

That reminds me...  People will get somewhat weird behavior if they mix
flex_array_append() and flex_array_put().  Is that OK?  Should
flex_array_put() modify ->nr_elements to point to the element past the
one that was just put()?  Should we perhaps drop the append() function
and the ->nr_elements variable completely?
