Hum...looks like a bug I've introduced in 1.5, as I've just tried with
1.0 and it worked.

No you are absolutely right. The current http sub module has a bug that
prevent the StreamAlgorithm to work as expected. Now why do you need to
use the http submodule for your project? Would it be easier to use
directly the framework classes? This way you don't have the http overhead.
I will fix the StreamAlgorithm so it can work with http like it was in 1.5.
