I've been trying to follow the logic in how the atimer stuff is supposed
to work. It registers a special timer fd that sets a timeout, and it's
supposed to be called back in timerfd_callback. And that happens if I'm
(for instance) idling in a `sleep-for'.
When Emacs is busy looping, we never get a callback -- presumably
because we're not reading any file descriptors in that case? But...
was the idea that this would work in a busy Emacs? I mean, events from
the keyboard/mouse are able to poke Emacs in a way that it realises that
it has a pending event to handle, but not the timerfd?
