Documentation
Marker for the start of the conditionally up-to-date region.
It is nil if there is no conditionally up-to-date region. The conditionally up-to-date region must be such that for any cached state S with position P in the conditionally up-to-date region, if at some point it is determined that S becomes correct for P, then all states with position >= P in the conditionally up to date region must also then be correct and all errors between P and the end of the region must then be correctly marked.
