I'm not sure there is any case in which S_proc_exception_raise really ought
to send a reply of its own.  If it's a bogus RPC, then it doesn't hurt,
since we're replying without trying the forward anyway.  (OTOH, it's bogus,
so the sender has no reasonable expectations of any kind.)  If the
forwarding send failed, then we're going to terminate the task and so it
certainly shouldn't matter if we reply to the kernel or not.
