[issue12902] help("modules") executes module code

[Terry J. Reedy]

#13902 is essentially a duplicate of this and I may close it.
I am thinking now that executing unknown amounts of unknown code from unknown modules is a really bad idea. If a module just crashes the system, as happened with the OP of the above, there is no way to tell what the culprit is. So if we do not disable 'modules', I thing it should just read directory names and forget about docstrings. In any case, output should be flushed as available if not now.
