+     *   PIN_RANGE: PIN_START PIN_LENGTH
+     *   PIN_START: big endian i32: offset in bytes of pin region from file start
+     *   PIN_LENGTH: big endian i32: length of pin region in bytes
+     * </pre>
+     *
+     * (We use big endian because that's what DataInputStream is hardcoded to use.)
+     *
+     * If attemptPinIntrospection is false, then we use a single implicit PIN_RANGE of (0,
+     * maxBytesToPin); that is, we attempt to pin the first maxBytesToPin bytes of the file.
+     *
+     * After we open a file, we march through the list of pin ranges and attempt to pin
+     * each one, stopping after we've pinned maxBytesToPin bytes. (We may truncate the last
+     * pinned range to fit.)  In this way, by choosing to emit certain PIN_RANGE pairs
+     * before others, file generators can express pins in priority order, making most
+     * effective use of the pinned-page quota.
+     *
+     * N.B. Each PIN_RANGE is clamped to the actual bounds of the file; all inputs have a
+     * meaningful interpretation. Also, a range locking a single byte of a page locks the
+     * whole page. Any truncated PIN_RANGE at EOF is ignored. Overlapping pinned entries
+     * are legal, but each pin of a byte counts toward the pin quota regardless of whether
+     * that byte has already been pinned, so the generator of PINLIST_META ought to ensure
+     * that ranges are non-overlapping.
