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.
