IIUC it was about to delete a single-window frame

> 30  org.gnu.AquamacsEmacs          0x0000000100018d9e delete_frame + 474 
(frame.c:1474)

so the first question is whether there were other frames left at that
time.

The downside of BLOCK_INPUT is that it makes Emacs unresponsive in the
sense that you can't even see a garbled frame when something goes wrong.
But yes - some general advice on why, whether and how BLOCK_INPUT should
be used would be very welcome.
