The problem is that you can't contribute anything that is related to
that class that you linked before. See

It's HttpResponseStream.cs all the *Bucket classes that then use an

I still don't think that allocating MemoryStream (256 bytes by default)

if the code is rewritten following what xsp does, this should not be a
problem any more.
