Arryn: I like linux as much as the next man, but linux is only a little better than windows with regard to what runs at ring 0/1. In fact, all kernel modules run in the same ring as the kernel itself: it is monolithic. BSD is the same. If you want a microkernel, which does not exhibit this problem, you want HURD or other exoteric kernels. Last time I heard, (true) microkernels have a 20% performance hit (according to Tannenbaum as far as I recall)

Graeme Dice: It is getting difficult to crash a modern, hardened linux system. E.g, fork-bombs doesn't work anymore. The trick you mention I do not understand. The kernel has no thread or process as such; so I don't understand how you can determine or exceed it's prioty?
