I feel that this "several days" figure is arbitrary.  You should be
able to turn days into hours by starting to run parallel jobs, finally,
and by using tmpfs for session and pot files.

When you're keeping a machine with GPUs a few percent busy for a long
time, preventing us from benchmarking stuff on it, this is just
unreasonable.  I'd prefer that you keep it 100% loaded for a shorter
period of time instead.

You just have to learn how to run parallel jobs.

Regarding fuzz.pl:

Sounds good.

Thanks,
