There is no such thing as a "cgi form" or "cgi window". Your cgi script
runs when the user requests a Web page, generates a page, and then ends. At
that point, python has stopped running. If your want the client's browser
window to close, that's not a python problem. If you want to invalidate the
download link after one successful download, you'll have to add a unique
identifier to the url and keep track of which identifiers are still valid.
