// Function:  checkChildPopupStatus

// Synopsis:  Because of cross site scripting we cannot simply close the comments popup and
//            refresh the comments page (popup comes up on www2b, comments pages are usually
//            on www) using commands like location.refresh so we must check if the popup
//            is closed and then refresh else check again in XXX ms.
