New issue 2264 by address@hidden: Line breaking can be slow with very  
wide paper
http://code.google.com/p/lilypond/issues/detail?id=2264

Lilypond takes 5 seconds to set this if there are 200 notes, 35 seconds if  
there are 400.

 \paper { paper-width= 10000\mm }
 {
%  \override Score.NonMusicalPaperColumn #'line-break-permission = ##f
   \repeat unfold 400 { b'4 } }

If we only want one line, the override above makes both cases quick.
