Comment (by isis):

 Not sure if this is correct in `queue_control_event_string()`:

 {{{
   int activate_event = 1;
   if (! flush_queued_event_pending && in_main_thread()) {
     activate_event = 1;
     flush_queued_event_pending = 1;
   }
 }}}

 Since `activate_event` will always be true. Is this what we want?  (I'm
 actually not entirely sure if you meant to always schedule the event
 because we just got it, but it seems maybe wrong since this also would
 ignore the `in_main_thread()` check.)

 Also, full disclosure: I skipped over reviewing the windows parts of these
 commits.

 The rest looks okay to me.
