I'm still a bit puzzled, because the default `exit' calls C exit(),
which means that some process somewhere is terminated in your current
setup.

But, in any case, the hook you want exists: scheme_exit is a global
variable in C that you can redirect to your own exit function.

I'm not sure where to point you at this time other than Inside MzScheme
(and this mailing list for specific questions).
