/* Note: The following is incorrect, but it's the best I can do

* The problem: Ensuring that both vertex arrays *and* index
* arrays are at the right position, and then ensuring that
* the LOAD_VBPNTR, DRAW_INDX and INDX_BUFFER packets are emitted
* at once.
*
* So why is the following incorrect? Well, it seems like
* allocating the index array might actually evict the vertex
* arrays. *sigh*
