Maybe use bar checks?

Subject: Unconventional score and unwanted stray staff lines

Hello everyone,

I tried to keep the examples minimal but I also needed to show the full extent 
of what is going on.

Attached are two Lilypond files and pdfs showing an unconventional score. Each 
part has the same number of notes but since the durations are random, each part 
ends at its own time.

badtest.ly and badtest.pdf show the default behavior. When a part ends, one of 
its staves continues on till the last part ends. I don't want this behavior.

test.ly and test.pdf do a better job of showing what happens with the 
workaround hack of adding s128 at the end of each part. The problem with that 
-- and I didn't include examples -- is that if all the durations are the same 
and end at a natural bar line, an extra empty measure is added at the end of 
each part. I can't check for this occurrence ahead of time in my own software 
as it would be insane to keep track of all of that.

You'll notice a lot of context commands all of which I think are necessary to 
get everything else to look as it should.

So I'm hoping someone has an idea about what's going on here and how to prevent 
those extra staves like in test.pdf

Also, these Lilypond files are generated automatically by another program I've 
created so the layout of the Lilypond file can't really be changed without a 
massive amount of work. Hopefully a solution won't require something like that.
