Thanks, Jim!
FWIW, here's a blog post by Francois Pesce who has experimented with
John the Ripper and JimF's "LinkedIn patch", successfully cracking 2
million passwords:

Some others have cracked more passwords, perhaps mostly by using GPUs -
@CrackMeIfYouCan reported over 4 million cracked after the first day -
yet 2 million is a fine number, and more importantly the blog post
details the approach, which I thought some john-users may find useful.
