How do I split up music in parts of equal length? Consider obscure cases such 
as
\new Voice \times 2/3 { << {c8 c8 \skip 4 c8 } { \skip 4 c8 c8 } >> }

BTW, I've been thinking about a generic solution to the grace note problems, 
which involves adding a moment with infinite negative grace part (i.e. "at 
time m, before all grace notes"). Would it be OK to use skip 1*inf, if that 
happens to work?
