Corrupt is a big word. Fail to implicitly call ASDF-defined image hooks.

It is probably a bug that there isn't a uiop/stream:clear-temporary-directory
that gets registered via uiop/configuration:register-clear-configuration-hook
in uiop/configuration. I can do it, though I'd rather someone else do it.

That said, even with that hook function defined and registered,
you still need to explicitly (call-image-dump-hook)
before you dump an image using implementation-specific tools, and
you need to (call-image-restore-hook) when you restart.

I don't believe there's any Franz bug.
It's a bug in how UIOP is not used properly.
These hooks probably need to be documented better, too.
