One of the BEGIN_RING counts is wrong. The BEGIN_RING overcounted, so it's not hazardous. This is because the next pointer is only bumped by how much was actually written, not the number of words that were supposed to be written according to BEGIN_RING's argument. Still, it should be fixed. Patch attached.
