I agree that the above is a real problem as it occasionally happens to
me and the reboots can be mighty disruptive.  It would be *very* helpful
if kernels could provide/enforce enough interactivity to allow users to
kill processes with "runaway disk usage".

And though I have no way to prove it, I think recent (eg. 2.6) kernels
do a slightly worse job in this area than historic ones (eg. 2.4, 2.2).

So are there ways to fix it?  And if so, how?
