[volunteergrid2-l] Backing up my DIRCAP

[Shawn Willden]

Hehe.

Actually, I think it's unlikely that anyone would notice a brute force
attack.

By default, my mapreduce jobs run at essentially "idle" priority, in terms
of both time and space -- they only get CPU cycles that nothing else (other
than similarly-prioritized jobs) wants, and if there's any memory pressure
(RAM tends to be the scarce resource) they get evicted -- but they do get
those idle cycles, and when they get evicted the management system will
fire them up wherever resources are available.

I've actually been thinking about trying a DES cracking run, just for fun.
