grace synchronization

[Kieren MacMillan]

Hello all, 

I'm running into a rather irritating grace synchronization problem — an 
acciaccatura in one voice is overriding an explicit page break — and so I 
wanted to know what it would take to fix the grace sync problem "once and for 
all".

I know of Issue 34 (and others) in the tracker, but here's my explicit 
question: What total bounty would cover a rewrite of the code so that grace 
note synchronization is not a concern at all for the user? I probably can't 
cover the whole thing, but knowing exactly the scope of the problem might lead 
others [who are equally frustrated by this issue] to chip in and get the fix 
funded.

Thanks!
Kieren.
