I would probably rewrite the other package in this case, but if you really can't I would suggest using the caller/DB trick below. It's really nasty and somewhat underdocumented, but it will probably work.

But in my view it's simple: the problem lies not in your code, it's in the other package. Fix the problem; fix the other package.
