url-bot can be DOSed by pointing it to an HTTP server that sends its response very slowly.
In such a scenario url-bot stops responding to any message and even times out from IRC, while still staying to connected to that slow HTTP server.
Here's some example server code that demonstrates that behaviour. It sends a space every second forever. I was able to keep url-bot busy for over 10 minutes that way.
