For the images, it tried handshaking 100 times and then marked the
connections as failed?

As I said before, the images are fetched from `url-queue', which gives
up if the image hasn't downloaded within five seconds.  Could that be
the case for you?

It runs every time something is available from poll, doesn't it?  Which
is what we care about.  I think.
