I don't think we can avoid reload(). A typicial design session has
several tools running, and it is a real pain to restart. Design
engineers often leave sessions open for several days.
What I will try to do is write the modules that are likely to be
reloaded in a way that minimizes the problems, accessing objects in
those modules *only* via their fully-qualified names, etc.
Again, these are interactive sessions. I don't think I will need
reload() as part of the code.
