Nate, I am glad things seem to be working somewhat better and I can see the smoke effect taking major cpu time.
For future reference, removing a child does not remove the event listeners on that child. I might, for example, want to remove a child from one container and add it to another, so, the child is preserved until all references to it are removed. Skim this link when you have time, start about half way down on destroying unused objects. http://livedocs.adobe.com/flex/201/html/wwhelp/wwhimpl/common/html/ww help.htm?context=LiveDocs_Book_Parts&file=performance_118_27.html This might not have anything to do with your issue at this point, but, it is still very usefull information.
