Comment (by laopsahl):

 So far I have only tested in a multi thread environment .

 If I read you correct I have to be able produce an invalid Topology by
 running in a single thread ?

 Can I run in partly in multiple threads by doing it this way ?

 {{{
 1) Break the input up into many grid cell
 2) Insert lines lines that are inside each cell and with min a distance
 like tolerance to cell border
 3) Insert the rest of the lines in a single thread

 }}}
