This may or may not be related -- but it's a problem I've been trying to
nail down for a while.

I most recently encountered it with high repro rates when using package
elfeed -- a feed-reader.

Elfeed keeps an index etc that can grow to 50mb plus -- it opens
those -- and updates them as well using idle  timers.


When those timers fire, and Emacs opens those archive files, it can pop
up the "file is x mb big, really open?" dialog. Now if this occurs while
you're at the keyboard, answering yes works -- and there is no
problem. However if this prompt occurs if you're away from your
keyboard,  or perhaps  working in  another window, then  it becomes
impossible to answer "yes/no" to that prompt from the  "file is too big"
dialog --- For elfeed the author checked in a fix that avoids the prompt
--- but the fact that an async generated prompt cannot be responded to
later is likely symptomatic of a deeper problem in input processing.
