score: Maybe fix _Thread_Lock_acquire()
The approach with the generation number was broken. The load/store of
the current lock, the thread queue and the thread queue operations were not
properly synchronized. Under certain conditions on a PowerPC T4240 old
thread queue operations operated on a new thread queue (NULL pointer).
