Not on all platforms, though.

I'll try bisecting when I have the time. In any case, it's just an 
implementation bug, not a blocker.

I mean, like, semantically: this new proposal is also visual/visible.

But 'visible-bell' is nil.

My #1 preference would be to make it all behave like (setq visible-bell 
t) on GNU/Linux does. This way we both get a proven behavior with no 
significant complaints, as well as consistency across platforms.
