Sorry, my former statement was not correct. If you switch off pipelinig, the 
2nd request is delayed until the 1st is completely processed. That's the way 
it should be but I can't remember if libwww really works this way. Only if 
you switch back to HTTP 1.0 you'll get a single connection for each request.

The patch still allowes pipelining, i.e. the 2nd request will be sent after 
the post data of the 1st request but before the result of the 1st request is 
being received.
