Interesting, I'll try and run with this. The mention of networks reminds me that any "max service time" variable is a tunable quantity depending on current conditions..
.. and sct's block device I/O accounting patches give us the current average request service time on a per-device basis. Multiply that up a bit and maybe you have your threshold for moving things to the head of the queue.
Cheers Chris
