Comment (by laopsahl):

 Here is a new test ​https://github.com/larsop/postgis/blob/svn-
 trunk/topology/test/regress/snapto_tc3.sql where there I have two almost
 parallel lines and then I add a crossing line and that fails with a error.
 This case can be solved by either increase tolerance level when adding the
 first lines or decrease tolerance level when adding the last line. But the
 main problem with that approach is that we add need the original data with
 a high tolerance level and the updated data with a lower tolerance level
 because we want to snapto the original lines if possible.
