Well, i thought we were talking mostly about what's in user-land core
dumps, not in kernel core dumps...
If you want to talk about kernel core dumps, well... There's a whole
lot of improvement to be had there. Really, the only memory that
should probably be dumped is the kernel memory plus the memory
belonging to objects mapped in the currently running process(es).
That'd be a great improvement; just because you have 2GB of memory
doesn't mean you should have to dump it all if the system croaks!!!
