// NOTE: The function definitions in this file can be consolidated with the
// definitions for the other induced methods. The only advantage of keeping
// them separate is that it allows us to avoid the very small loop overhead
// of executing one iteration of a for loop, plus the overhead of calling a
// function that does nothing (ie: the _cntx_init_stage() function).
