* ruby_vm_at_exit registers a function _func_ to be invoked when a VM
|

* passed away. Functions registered this way runs in reverse order
|
|
* of registration, just like END {} block does. The difference is
|
|
* its timing to be triggered. ruby_vm_at_exit functions runs when a
|
|
* VM _passed_ _away_, while END {} blocks runs just _before_ a VM
|
|
* _is_ _passing_ _away_.
|
|
*
|
|
* You cannot register a function to another VM than where you are in.
|
|
* So where to register is intuitive, omitted. OTOH the argument
|
|
* _func_ cannot know which VM it is in because at the time of
|
|
* invocation, the VM has already died and there is no execution
|
|
* context. The VM itself is passed as the first argument to it.
|
|
*
|
|
* @param[in] func the function to register.
