This means it is possible for a control to modify its own
node hierarchy in a way that might have caused random skipping
at best and index out of bounds exceptions at worse.
Also, users can iterate over children and detach them at the
same time using standard for each constructs.
Performance is the same for me though I'd expected it to be
at least slightly faster given that most inner loops now use
direct array access. My scenes must not exploit this much.
