[Cuis] 'Internals' questions

[Phil (list)]

I need to do a couple of things that are mucking around a bit at Cuis/VM
internals and could use some help getting started:

1) How can I have one block called just after the image starts up (i.e.
all other image state has been restored (esp. FFI) and things are about
to be handed off to the user) and another just before the image saves
and/or shuts down.

2) What's the best way to get the pathname for the currently running
image?

Thanks,
Phil
