Comment (by dbaston):
Yes, the cascaded union for lines is very expensive in some cases. I put
together a performance benchmark that's like the #982 case (many short
lines), and removing the cascaded union improves performance by about 85%.
So it might make sense to use the cascaded approach only if the standard
approach throws an exception.
