Dumping /dev/zero to the console

Here is a neat trick to make your linux box essentially unusable:

On linux console, even as a non-priv user, do a:

% dd if=/dev/zero bs=1024k

Now switch to another console (or even X) and try to do anything useful
and see how the box behaves. Same result with v1.2.13 and v2.0.7 kernel.
