The reason I got this message was that I didn't check if an entry for
the socket already was present in the map from sockets to
QSocketNotifier/HTEvent tuples.

The reason the notifiers weren't yet unregistered was that the HTTP
1.1 connection was still open, and stayed open until it was closed by
the server.

Right now I'm overwriting the previous HTEvent* value with the new
event, which brings me back to the question I had in
        http://lists.w3.org/Archives/Public/www-lib/1999JulSep/1006.html
ie. can more than one event be registered for a particular socket at
the same time?

I would think that the answer is "no", but I'm not sure.
