Right.

It's better than nothing, though, and will unwedge Emacs in many
situations.
But if we had this facility (i.e., a way to make Emacs call some
function after `C-g'-ing a lot during redisplay), then we can start
experimenting -- and users can, too. So I think having a
`break-during-redisplay-function' variable that specifies something to
be called in these situations would allow some possible progress in this
area.
