Hi<br>
<br>
I have an application which uses web2. In good twisted style I'm writing tests for it, and using trial.<br>
<br>
When performing some rather simple page retrievals a get a lingering http channel. Setting<br>
twisted.internet.base.DelayedCall.debug = True<br>
I get this trace:<br>

This if course makes sense, especially if the server lost its
connection. I am doing cleanup in tearDown (calling stopListening() on
the port), but trial still complains. Canceling the call, and calling
it manually in tearDown, doesn't appear to help either. How do I make
it shut it up in a proper way?<br>
<br>
<br>
PS. I'm rather pleased with the web2 framework, especially the stream
framework (once I got my head wrapped around it), but it is hard to get
an overview of the internals. A brief description of the design,
philosophy, what was wrong with web(1), etc. would be very nice (I do
realize that web2 is a moving target).<br>
