hmm - no need to do fancy callbacks ;-)
just "visit every node in a tree" and return the node.
  as a plus keep in root some sort of 'generation' counter
  which gets bumped once a node gets inserted or deleted from
  the tree. when a user function walks the tree you are able
  to detect that some other thread has altered the tree.
