I'm thinking that any increase might be unsafe, and that we should just
leave the variable be.  We don't want to crash an Emacs where the user
has already increased the limit.

That's true.  But if there's a chance that Emacs may crash by the user
holding down `y' a bit, then that's no fun, either...
