I think it means that the freeze wasn't a freeze, but just a very long search for a font that could support the character. It was made even longer by using up a lot of memory, which caused paging and slowed Emacs down. Not sure why it used up so much memory, perhaps that's due to some very large font, or maybe it's a bug in the macOS code which is involved in the search. Having Symbola installed is a Good Thing anyway, because Emacs by default will try to use it for many unusual characters.
