Good point. In that case, you'll need to override 
Time_scaled_iterator::process() to watch now_mom().main_part_ to insert 
the events "just in time".

I've heard you about this solution before, but I'd like to see a 
proposal first, especially because you're already dealing with 3 
branches (parser rewrite, old stream bugfixing, new stream functionality).

FWIW, inserting grace "patches" of -1*50 will insert extra 
paper-columns, which will mess up the spacing.
