Note that you can get the same issue without duplicate

Well don't do that... :-)
Looks like a fly in the ointment. The most straightforward
solution is to always add the opAdd/Release cycle when passing
globals to impures. That's probably good enough. You probably
don't pass a global to an impure very often anyway.
