ISTR, when I added that check to Feval initially, I found that it is
(was?) sometimes called with input blocked, although only from places
where code in BLOCK/UNBLOCK_INPUT is kind of a ``critical section''
that must not be interrupted by event handling.  It felt like a good
idea to make real event handling and these critical sections
distinguishable.
