Well... Imagine me wanting to crack your machine. So I'll sit on same
subnet, and make it crash. (Crash is easier than crack ;-). I'll make
your machine load shadow into memory. And then, I'll just listen.


PS: But yes, in case we really need coredumps, this is probably the
good way to do it.
PS/2: If someone is interested, I've patch for magic sysrq keys to
work over network, including dmesg-like dump.
