Is nptl 0.41 still "considered more or less x86-only." like nptl-0.40 or is it intended for general use? PPC (and I suspect S390 and SH) is broken due to the futex requeue change. kernel-features.h has __ASSUME_FUTEX_REQUEUE but that is not used in the common ./libc23/nptl/sysdeps/pthread/pthread_cond_*.c source. It seems pthread_cond_wait.c, pthread_cond_signal.c, and pthread_cond_broadcast.c where changed to use __data.__mutex and lll_futex_requeue without conditioning it on __ASSUME_FUTEX_REQUEUE. What is the general intent for this; 1) all platforms should assume the new kernel and ignore __ASSUME_FUTEX_REQUEUE, 2) or nptl should honor __ASSUME_FUTEX_REQUEUE and continue to support pre 2.5.70 kernels?
