Somehow I was unlucky enough to find the example that worked
{ \repeat unfold 22 b2
  \autoPageBreaksOff
  \repeat unfold 320 b2
  \once\autoPageBreaksOn
  R1
  \repeat unfold 320 b2 }

I tried to figure out why LilyPond's page-breaking usually misses these
opportunities, and concluded only that LilyPond's 'constrained-breaking'
algorithm takes a strange approach.
