The removed code is slightly different in that it gracefully handles the situation where m_parent->m_children doesn't contain "this." Do you know if that's important?

I can't think of a case where m_parent exists but m_parent->children doesn't contain "this". Do you happen to know how that might happen?

I'm not sure.

Then we could try with an ASSERT() and check if it's hit.
