    Along these lines; wouldn't it be neat if there was a sysctl
    to leave a segfaulted or aborted process around so that you
    can attach a debugger to it and find out what went wrong (and
    may be even correct it!)? Debugging a live process (even if
    fatally injured) yields more clues as you can poke around at
    its I/O connections, its caller process etc. A separate
    program can be used to create a coredump if you really wish
    to preseve the dead body for later autopsy.
