/* Some notes:
This program is a great example of how allocating and freeing
memory is very screwed up:
* The Stream allocates the name, we have to free it.
* The Coder free's its Stream when the Coder is free'd, but we
were the ones to create it.
These difficult and ad-hoc rules will be fixed in the future.
