There are times when I'm constantly adding and removing a child.  For example, when I'm trying to throw out alerts to a user, I'll addChild( alertMc) then removeChild( alertMc ) when I'm done.  Sometimes things get a bit tricky and I'll mistakenly call removeChild() when content is no longer available  on stage.  To remedy this, what I do now is call my function removeContent( stage, "nameOfMc_Loader_anything") and it will first make sure that my target is on the stage before it removes it.
