// causing the ORB to attempt to handle several connection establishments
// at one time. Apparently, under certain conditions, it will throw the
// TRANSIENT exception to tell the client application to "try again later".
// The analogy is making a phone call. Sometimes you get a busy tone.
// This means "try again later".
// This helper function will retry until the connection establishment
// works - or until it decides that enough is enough.
