There is not reliable way, as Zope may die unexpectedly (e.g.
caused by a signal).

"refresh" lets you control that some modules are not reloaded
during a refresh.

There is no hook to intercept module deletion.

There is a hook to get control at program exit.
It is called "atexit" (or similar).
As modules usually do not disappear by themselves, this
may be enough. As said, it is not reliable in case of abnormal
terminations.
