I guess you are referring to painting ways that leave the visible

Handle the node as if it did not exist. Skip it (if apropriate with
a log-message).
Works fine for me in rendering, routing and any of the graph-algorithms.
A simple matter of making a program robust instead of just stable.
If input is slightly wrong a program should be able to continue it's task
nonetheless (as long as it's no verifier or the consequences of a slight
error would be dramatic.).
