At least you can alleviate it!

The two issues seem to be important to fix. And the issue here already has a
patch that is basically approved!

The problem is not only a lengthy pause (which is annoying but it is a
different issue), it is also that after the pause, Emacs may spend a several
*minutes* printing candidates, slowing the whole computer down with it. A limit
of 1000 seems almost too much, 150 or so seems much more manageable.

Please, can you commit your patch so at least there is some progress on this?
