[luatex] robustness of node.traverse

the manual is quite terse about node.traverse(). I'd like to know what
operations (insertion/removal) on the node list given as argument to
node.traverse() are save in a loop like
for n in node.traverse(head) do
I'd guess removing the current node in the loop body is not a good idea.
But anything else? Sure, inserting before/after the current node
changes the current node, too. But that shouldn't be a problem, should it?
