I would think that z-index is the better solution. Your mechanism for
opening the popup ( rather than the popup itself) should be the one making
the determination as to which z-index to use.
Beyond a "system error" type of message, I personally don't think it's good
UX to have popups throwing popups... but a requirement is a requirement.
