Questions about throw-on-input

[Ivan Yonchovski]

Hi all,

I have few questions regarding throw-on-input:

1. In the following example:

(dotimes (_ 10)
  (message "Length %s"
           (length
            (let (result)
              (catch t
                (let ((throw-on-input t))
                  (dotimes (counter 10000000)
                    (push (number-to-string counter) result))))
              result))))

.. after I execute the following block each of the 10 computations will be
canceled after pressing C-n for example, how do I force the handling of
the command to be processed? I tried redisplay but it does not help.

2. Consider the following pieces of code:

(message "Length %s"
         (length
          (let (result)
            (catch t
              (let ((throw-on-input t))
                (dotimes (counter 10000000)
                  (push (number-to-string counter) result))))
            result)))


(run-with-idle-timer
 0.0
 nil
 (lambda ()
   (message "Length %s"
            (length
             (let (result)
               (catch t
                 (let ((throw-on-input t))
                   (dotimes (counter 10000000)
                     (push (number-to-string counter) result))))
               result)))))

The issue is with the second block, it seems like throw-on-input is
disregarded when used in run-with-idle-timer. Can anyone confirm if this
is a bug/desired behavior or I should use something else if I want to
run cancelable tasks in on-idle?

Thanks,
Ivan
