Comment #7 on issue 185 by address@hidden: RhythmicStaff squishing chords  
should produce single notes
http://code.google.com/p/lilypond/issues/detail?id=185

Objects don't "belong" to voices.  The correlation is not between object  
and context-specific engraver instance, but between announcement and  
context-specific engraver instance.  If you don't listen at Voice-level,  
there is no Voice-level correlation.

It turns out that collision avoidance is not actually done at Voice-level:  
my example looks fine by just adding
\layout {
  \context {
    \RhythmicStaff
    \consists "Collision_engraver"
    \consists "Rest_collision_engraver"
  }
}
Obviously, this will acerbate the problem of this issue.

Maybe we need an engraver listening to Stems and shooting all NoteHeads  
except the first per stem.  This should take place before collision  
resolution.
