The point is... if you execute code on a Freenet node you got from someplace
you-don't-know-where, it can do all kinds of weird things to your system.
All I can say is that I wouldn't want to do that to my system.

It's phrased brilliantly of course!!!! ;-)
With "you" I meant the attacker that tries to bring down a node. If we
implement Freenet processes as your proposed, it will be very easy for that
person to bring down the node - sHe just sends the node some code that
contains an endless loop.
