Funny you should mention that...

I have an implementation of a retest manager in git:

    https://github.com/davesteele/piuparts/commits/retest-manager

It adds idle state to master, for central monitoring of the overall
system idle state. A new reschedule_oldest_logs monitors for this
sections-wide idle, and deletes logs according to Holger's algorithm
when it sees it.

I haven't brought it forward on develop, because there are a couple of
areas of contention with work that Andreas has been doing, in sleep
idle processing and in the configuration file. The integration
strategy needs some discussion.

To start, I used "idle" instead of "idle $N". That should make for a
simpler slave, and avoid a thundering herd of connections to master.
