      During a concurrent start pause when class unloading, we do two passes over the CLD.

      In the first pass we let one thread claim the CLD work; in the second pass we do not, which means that threads do unnecessary duplicate work as the phase walks over the CLD singly-linked list (i.e. there is no work distribution anyway).
