Suppose a company wants to develop a proprietary, close source 
product and uses the following method of developing it:

Start with a GPL program.

Modify it.

Continue modifying it until no original code remains.  Perhaps 
through hundreds of modifications.

Done.

The question ....  At what point does GPL no longer apply?

I am not considering doing this.  I want the answer to be "GPL always 
applies", but have some concern that it doesn't.
