[Seaside] Zinc - Twitter - Streaming API - Long lived connections

In my little project (SCouchDB), i also had to deal with same situation:
 - a couchDB server API using a long-lived connection(s) to notify
observers about database updates,
which can be used for replication of data or watching for updates etc.

So, the idea is to not wait till all data will arrive upon HTTP
request, but answer a stream (which represents a contents),
once http response header is arrived. Then user code may request
#contents, which will force stream to read all data upon
connection is closed (or up to content length, if it specified), or
user may consume data in portions by using a #next /#next: messages to

This is useful also for cases, when amount of data to transfer is big,
so you don't collect it into a huge buffer and only then hanging over
to user,
but you letting a user to process data in portions, once it arrives via wire.

But it should not be too difficult to write some loop that keeps on consuming responses and to deal with them in a streaming fashion.
