Comment (by laopsahl):

 This sounds like a good idea.

 So if I have a set of lines to add, how do I  find the edge row and maybe
 face rows to lock ?

 (I have tried to block other  threads based on input geometry and faces,
 but I never got it to work 100%, but if remove this blocking  totally in
 step 3 [https://github.com/larsop/resolve-overlap-and-
 gap/commit/874f843c58921c5e2fca18240aef60f15bfc6b58#diff-
 0ec63b6826e9888305fd67d50bf428e1 ]totally the server core dumps quite
 fast)
