It's not that extreme. It's natural for a user to get the whole list and then
use C-s to find the desired character.
Also, there's a problem even in less-"extreme" cases. I just now tried 'C-x 8
RET B TAB', which lists every character whose name starts with "B", and this
took about 18 s on my platform, whereas with Emacs 24.5 it is almost
instantaneous. 18 s is waayyy to slow for this sort of user interaction.
Stefan's suggestion of a config var sounds good. It's a bit late to be adding
features to the emacs-25 branch, though, so I'm inclined to revert in emacs-25
(with a "do not merge to master") and add a customizable var in master.
