Any reason why not? We kill things in a staggered process, starting by
simply disabling cron, and only actually killing at the last possible
moment. We can make sure we start with SIGINT that will trigger stack
unwinding.

We can put a ulimit on it - that will cause a MemoryError exception to
unwind the stack, rather than the process being hard-killed.
