For large trees the cleanup can actually take a long time if you do it
piece by piece. Given that the operating system cleans up all the
applications resources on exit anyway, there was never a compelling
reason to do it.

Yeah, the delete mgr will clean up the scene, too, so if you don't have
another reference to it, you get double frees, which are not handled
very gracefully.
As I said, I'm personally more worried about leaks in a running
application, so those 140k don't worry me very much.
