// Note that despite what it looks like this test does leave windows open
// after the test finishes. That's because some of the window.open calls
// trigger an exception but still open a window. Because of the
// exception, winsToClose.push is not executed and we have no reference
// to the window. So far there is no known way to get a reference to it.
// It was also tried to give each opened windowed a named target, save
// that list of targets, and use window.open("", targetname) to get a
// reference to the window. That also doesn't work because either the
// window.open calls never end and this page never loads, or if it does
// load after a finite time then still some windows are left open for
// some reason.
