I didn't yet take a good look at the code, so I may not make sense,
but: if the problem with getting Emacs to check atimers is that it
needs an input event, then does it help to define a one-time timer
in addition to arranging the atimer? When we have an active timer, we
artificially reduce the timeout for pselect so that it expires before
the expected timer -- maybe that is all that's needed, to cause the
input loop crank one more revolution?
