Well, if it's an 18 page score, then there are lots of page break options,
and so there would be lots of calculations.   2 billion seems like a lot,
but there are a lot of ways to figure out line and page breaks in 18 pages
of score....

ly_scm2interval is part of the beam scoring code.  So that might be where
many of the calls come from.

I'm not sure what the fix might be.
