 The patches to convert ReadActivity to stream tubes (attached to #4297)
 work with Salut, but not with Gabble. This appears to be because the
 connection manager proxies the TCP connection and changes the message
 boundaries; GlibURLDownloader thus gets a short read (len(data) <
 self.CHUNK_SIZE) and decides that the download has finished.

 TCP streams are bytestreams, not message streams, so should make no
 assumptions about message boundaries. The downloader should instead use
 the Content-Length header, probably.

 I'll probably work around this in #4297 by not using HTTP.
