This is a diff from Ken Chen, who sent it to me a week ago and received
the claimed prize $256. I think it's partially based on Jan's code,
while if fixes the bug Jan mentioned (as far as I know).
It does the following:
- allocate loop dynamically on the fly
- allocate one more (spare) loop eac

dev nodes by itself, so you need to do it (à la mdadm)
I'm afraid that this would break a lot of things, for example mount -o
loop will not work anymore unless you create /dev/loop* manually first,
