+	// The same strategy of splitting the buffer in three is used but the
+	// combining calculation is different; the complete derivation is explained
+	// below.
+	//
+	// -- The basic idea --
+	//
+	// The CRC32 instruction (available in SSE4.2) can process 8 bytes at a
+	// time. In recent Intel architectures the instruction takes 3 cycles;
+	// however the processor can pipeline up to three instructions if they
+	// don't depend on each other.
+	//
+	// Roughly this means that we can process three buffers in about the same
+	// time we can process one buffer.
+	//
+	// The idea is then to split the buffer in three, CRC the three pieces
+	// separately and then combine the results.
+	//
+	// Combining the results requires precomputed tables, so we must choose a
+	// fixed buffer length to optimize. The longer the length, the faster; but
+	// only buffers longer than this length will use the optimization. We choose
+	// two cutoffs and compute tables for both:
+	//  - one around 512: 168*3=504
+	//  - one around 4KB: 1344*3=4032
+	//
+	// -- The nitty gritty --
+	//
+	// Let CRC(I, X) be the non-inverted CRC32-C of the sequence X (with
+	// initial non-inverted CRC I). This function has the following properties:
+	//   (a) CRC(I, AB) = CRC(CRC(I, A), B)
+	//   (b) CRC(I, A xor B) = CRC(I, A) xor CRC(0, B)
+	//
+	// Say we want to compute CRC(I, ABC) where A, B, C are three sequences of
+	// K bytes each, where K is a fixed constant. Let O be the sequence of K zero
+	// bytes.
+	//
+	// CRC(I, ABC) = CRC(I, ABO xor C)
+	//             = CRC(I, ABO) xor CRC(0, C)
+	//             = CRC(CRC(I, AB), O) xor CRC(0, C)
+	//             = CRC(CRC(I, AO xor B), O) xor CRC(0, C)
+	//             = CRC(CRC(I, AO) xor CRC(0, B), O) xor CRC(0, C)
+	//             = CRC(CRC(CRC(I, A), O) xor CRC(0, B), O) xor CRC(0, C)
+	//
+	// The castagnoliSSE42Triple function can compute CRC(I, A), CRC(0, B),
+	// and CRC(0, C) efficiently.  We just need to find a way to quickly compute
+	// CRC(uvwx, O) given a 4-byte initial value uvwx. We can precompute these
+	// values; since we can't have a 32-bit table, we break it up into four
+	// 8-bit tables:
+	//
+	//    CRC(uvwx, O) = CRC(u000, O) xor
+	//                   CRC(0v00, O) xor
+	//                   CRC(00w0, O) xor
+	//                   CRC(000x, O)
+	//
+	// We can compute tables corresponding to the four terms for all 8-bit
+	// values.
