The linux kernel "out of memory" killer will kill fairly random
processes (the last one asking for more memory, if I recall correctly)
when the machine run out of memory. Earlier it could also kill init. I
am not sure that is the case any more. There is also memory handling
inside the kernel that I suspect will cause problems if the kernel run
out of memory. I have not seen that myself, so I am unsure if it really
can happen after the kernel is able to get started.

No idea.
