The stream is freed of automatically! Think of the streams as objects
hanging of each other making a stream chain:

	STREAM_1 --> STREAM_2 --> ... --> STREAM_n

STREAM_1 is the first stream where data is put directly from the network and
your HTFWriter stream comes in as STREAM_n. When STREAM_1 is freed when no
more data is arriving and the socket closed, all stream objects down the chain
are automatically freed. You can see this by looking into the free method in
any of the streams. It looks to see if there is a stream object hanging off it
(normally called the target or sink) or it is the last element in the chain.
If a target is found then it is freed.

BTW: A stream doesn't have to have a output, a good example of the opposite is the
HTBlackHole stream that just absorbs data!

You can see a nicer picture of this at
