        <pre>Hmm, this assertion is there to fix issue where people are inappropriately getting the structure of an object while they are destroying it. However, detach are trying to access the global object of some executing frame, which is unusual, but in this case should be ok. I'm not sure what the best solution is here... :/</pre>
