I should have read the code more closely:
void
init_atimer (void)
{
#ifdef HAVE_ITIMERSPEC
# ifdef HAVE_TIMERFD
/* Until this feature is considered stable, you can ask to not use it. */
timerfd = (egetenv ("EMACS_IGNORE_TIMERFD") || have_buggy_timerfd () ? -1 :
timerfd_create (CLOCK_REALTIME, TFD_NONBLOCK | TFD_CLOEXEC));
# endif
if (timerfd < 0)
{
struct sigevent sigev;
sigev.sigev_notify = SIGEV_SIGNAL;
So if we have timerfd, the alarm stuff is not set up.
And... uhm...
EMACS_IGNORE_TIMERFD=t ./src/emacs
doesn't disable it, either? That egetenv call returns NULL even if I
start Emacs like that? Odd. Anyway, if I forcibly disable timerfd,
then the atimers work like they're supposed to, and the correct code
paths are triggered at the time they're supposed to.
So the timerfd stuff doesn't actually work.
