The tedium of monitoring reference counts.
Maybe you don't need a copy on the other side.
Keeping your eye on the reference count.
On the nature of streams.
Making sure things are ready for the person who comes after you.
Creating an identical object on the other side.
Starting with a marshaler that has no special features.
Pretend you're an oracle.
The outermost simple layer, and the more complex inner layer.
A little too much copy/pasta.
