Yep. The final hang was in the mini-buffer, right after "M-x".
I am sure that wide-column shouldn't be doing anything in the
mini-buffer, but there is not check for it.

It's an overly complex function which calls effectively changes the
colour of the cursor once a line gets too long. I have been suspicious
about this function for a while, but I use it in lots of buffers and it
has not changed for years (probably a decade).
