(I'm going through old bug reports that unfortunately weren't resolved
at the time.)
It probably won't continue working, but it's hard to say.

I wonder whether there's been any discussion about handling `C-g' during
redisplay. For instance, if the user hits `C-g' six times in a row
during redisplay, that should be an indication that perhaps Emacs should
stop doing what it's doing -- and, for instance, switch on so-long-mode.
Eli, would it be possible to implement something like that?
