There are no such situations anymore in an optimal userlevel implementation. The last problem (in pthread_cond_signal) was fixed by the addition of FUTEX_WAKE_OP. The userlevel code you're looking at is simply not optimized for the modern kernels. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
