Ok, I'll have a look at implementing this (might take a bit until I get time, though).

If the author or maintainer intends to look into, he or she should probably just write a short email saying that he will do so; failing this, a developer or AFP editor who is annoyed by the failures could write the first email.

Good point. A little communication will go a long way for this. The initial burden on kicking off the discussion should probably be on the editors, calling for assistance if something is too much to update in the normal submission process.

I still have to look into the current fairly large set of new failures. My guess from a brief look at the log is that something is taking up a large amount of CPU somewhere, triggering timeouts all over the place.
