i don't think that's much of a risk, actually. i've used features like this on mainframes and under Solaris for years, and never had a problem like this. it's easy to reboot a small program that does this, or have logic that rereads the VTOC before dumping. even so, you'd have to have a pretty pathological kernel to experience something like this, IMO.
