not to mention that utrace could be used to move most of the ELF
coredumping code out of the kernel. (the moment you have access to all
crashed threads userspace can construct its own coredump - instead of
having the kernel construct a coredump file) Roland's patch does not go
as far yet, but it could be a possible target.
