// When explorer launches a Windows (GUI) application, it displays
// the "app starting" (the "pointer + hourglass") cursor for a number
// of seconds, or until the app does something UI-ish (eg, creating a
// window, or fetching a message). As this launcher doesn't do this
// directly, that cursor remains even after the child process does these
// things. We avoid that by doing a simple post+get message.
// See http://bugs.python.org/issue17290 and
