Not really related to achieving what you're asking, but if you have access to
the DNS records for the domains you're dealing with (and you have enough
leeway time), wouldn't it just be simpler to change your TTL to something like
60 seconds so the propagation time happens much more quickly?

I guess you have to chance things with misbehaving DNS servers that don't
honor TTL's and such ...
