    devel/tevent: clamp far-future poll(2) timeout to avoid a busy-loop
    
    When a timer is scheduled far enough in the future,
    tvalp->tv_sec * 1000 overflows the int millisecond value that
    poll_event_loop_poll() passes to poll(2). poll(2) then fails with
    EINVAL and tevent spins in a busy-loop instead of sleeping. Clamp
    the computed timeout to INT_MAX in that case.
