ACK, that's my feeling as well. Even though I've no access to the said
machines, I seriously doubt edos-debcheck can take 10 minutes or so.

Sure, but as I discussed it will be yet another ack, because currently
edos-debcheck has no notion of sources. It can be done
nevertheless. Still, before going that way, please check whether
python-apt is installed or not.

The add-sources.py wrapper uses python-debian which only recommends
python-apt. If the latter is not installed however, Sources parsing
happens in pure python instead of using libapt-pkg. That can be a
serious difference in performances ...

Let me know.
