 While using the posts_per_page in the pre_get_posts, if you set it to -1.
 It will output all the posts. The issue is that if you use this with the
 main query on a taxonomy archive page, then it will create unlimited
 number of subpages with all the same content as the main page :
 taxonomy-1/
 taxonomy-1/page/2/
 taxonomy-1/page/3/
 ...
 taxonomy-1/page/500/
 etc...

 It is probably not really the expected behavior...
