* configure.ac (HAVE_TIMERFD): Define only if TFD_CLOEXEC works, since the code leaked file descriptors to children when !TFD_CLOEXEC. (HAVE_TIMERFD_CLOEXEC): Remove; no longer used. * m4/clock_time.m4 (gl_CLOCK_TIME): Don't check for clock_getres. This reverts the previous change to this file, so it matches gnulib again. * src/atimer.c (TIMERFD_CREATE_FLAGS): Remove; we now assume TFD_CLOEXEC. (alarm_timer, alarm_timer_ok, set_alarm, init_atimer): Fall back on timer_create if timerfd_create fails at runtime. (resolution) [HAVE_CLOCK_GETRES]: Remove; we now rely on the kernel primitives to do resolution. All uses removed. (timerfd) [!HAVE_TIMERFD]: Define to be -1, for convenience. (turn_on_atimers): Clear timer_create-based timers too, for consistency.
