   We should probably remove support for "dead kernels". It has never worked
in 2.x anyway and I'm fundamentally opposed to hacking in cruft to drudge
around in the kernel's crash dump and attempt to parse paging data structures.
That's what debuggers are for. That goes against the principal of why we're
using procfs in the first place.
