+ * 4 GiB / 4 KiB * (64 bit / 8) = 8 MiB
+ * just for the data, plus the additional data overhead for the red-black
+ * tree used for data sorting (if each rb-tree element stores 3 address
+ * and the word-aligne color, the total size grows to 32 MiB).
+ * - std::bitset<N> is not a good fit because requires a priori knowledge,
+ * at compile time, of the bitset size.
+ * - std::vector<bool> is a special case of vector, which uses a data
+ * compression that allows reducing the space utilization of each element
+ * to 1 bit. In detail, this data structure is composed of a resizable
+ * array of words, each of them representing a bitmap. On a 64 bit
+ * device, modifying the whole 4 GiB snapshot grows this container up to
+ * 4 * GiB / 4 KiB / 64 = 64 KiB
+ * that, even if is the same space requirement to change a single byte at
+ * the highest address of the snapshot, is a very affordable space
+ * requirement.
