As a practical matter, I agree.  As a programmer, I understand the concept
of a "thread of execution".

Does the copyright statute?  In other words, does the law see a series of
instructions executed in a certain order as a derivative work, regardless of
how those instructions came to be excecuted in that order?

Imagine I have two novels.

On page 100 of Novel A, there is an instruction:  Open up Novel B, turn to
Chapter 7.  When finished, come back to this point and continue reading.

As the reader, (the processor in this analogy) I follow these instructions.
My "thread of execution" takes me from Page 100 in Novel A, to Chapter 7 of
Novel B, and back to page 100 of Novel A again.

Are Novel A and B now a derivative work?
