/* Split LINEAR into a linear sequence with low values and an erratic
sequence with high values, put the linear one (of longest possible
length) into LINEAR and the erratic one into ERRATIC. This is O(N).
Because the longest linear sequence we are trying to locate within the
incoming LINEAR array can be interspersed with (high valued) erratic
entries. We construct a chain indicating the sequenced entries.
To avoid having to allocate this chain, we overlay it onto the space of
the ERRATIC array during construction. A final pass iterates over the
chain to determine what should be placed in the ERRATIC array, and
what is the linear sequence. This overlay is safe from aliasing. */
