+ * equal or the second is the "next" of the first. Similarly there are
+ * two end blocks. Thus the queue either looks like this:
+ *
+ * A -> B -> ... -> C -> D
+ *
+ * Or like this, or some combination:
+ *
+ * A/B -> ... -> C/D
+ *
+ * However, there's only one beginning/end chunk offset. Now the
+ * question is, which of A or B is the actual start? I.e. is the chunk
+ * offset an offset inside A or B? It depends. I'll show a typical read
+ * cycle, starting here (read pointer marked with a *) with a chunk
+ * offset of 0:
+ *
+ * A B
+ * _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
+ * |_|_|_|_|_|_|_|_| -> |*|_|_|_|_|_|_|_| -> |_|_|_|_|_|_|_|_|
+ *
+ * Once the pointer advances far enough, the hardware decides to free
+ * A, after which the read-side state looks like:
+ *
+ * (free) A/B
+ * _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
+ * |_|_|_|_|_|_|_|_| |_|_|_|*|_|_|_|_| -> |_|_|_|_|_|_|_|_|
+ *
+ * Then after advancing the pointer a bit more, the hardware fetches
+ * the "next" pointer for A and stores it in B:
+ *
+ * (free) A B
+ * _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
+ * |_|_|_|_|_|_|_|_| |_|_|_|_|_|_|_|*| -> |_|_|_|_|_|_|_|_|
+ *
+ * Then the read pointer advances into B, at which point we've come
+ * back to the first state having advanced a whole block:
+ *
+ * (free) A B
+ * _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
+ * |_|_|_|_|_|_|_|_| |_|_|_|_|_|_|_|_| -> |*|_|_|_|_|_|_|_|
+ *
+ *
+ * There is a similar cycle for the write pointer. Now, the question
+ * is, how do we know which state we're in? We need to know this to
+ * know whether the pointer (*) is in A or B if they're different. It
+ * seems like there should be some bit somewhere describing this, but
+ * after lots of experimentation I've come up empty-handed. For now we
+ * assume that if the pointer is in the first half, then we're in
+ * either the first or second state and use B, and otherwise we're in
+ * the second or third state and use A. So far I haven't seen anything
+ * that violates this assumption.
