// A long key page consist of a header part, a key data part and an index part. The
// page starts with a header of size HEAD_SIZE. As you can see below, not every word
// in the header is used. After the header comes the data part, where the actual
// keys are stored. A key is always inserted after the existing keys in the data
// part. If we have a fragmented data part and a new key doesn't fit after the
// existing keys we reorganize the keys. The index part starts at the end of the
// page and grows towards the end of the data part. This means that the limit
// between the data part and the index part is floating. Each inserted key have a
// word in the index part that describes size and position of the key in the data
// part. The free indexes in the index part are single linked.
