Well what are they doing then? Still running the requests? This is a fundamental problem with fetching stuff over HTTP from Freenet with a low timeout - if your tool moves on to add more requests, the old requests haven't failed, they are still going. Having said that it may eventually be possible to detect connection closed - in 0.5 there was a hack for it.
