In my short experience I/O is not much of an issue when using async
mounts, I can greatly increase throughput by running several tinderd
Unfortunately I mustn't queue more than one job per build in this case.
I was thinking of hacking tinderd to deal with locked builds more
gracefully (i.e. not marking a queue entry failed) and fix the rc.d
script to manage multiple tinderd instances.
