    abort2: Generate a core dump
    Call sigexit rather than exit1 so that a core is generated.
    If running the SIGABRT handler is desired, this would need to use
    kern_psignal() instead.  In that case a userspace wrapper in libc
    would be needed to force an exit if the handler doesn't exit.  Given
    that abort2(2)'s intended use case is when userland is in a
    sufficiently bad state such that it can't safely call syslog(3) before
    abort(3), a userspace abort2(3) wrapper in libc might be dubious.
