    Now I'm sure this is the real cause of "Wrong type argument: commandp"
    error that is found in some Carbon Emacs distributions that preloads
    international/encoded-kb.elc.

Suppose that the pure structures here were not modified.
(That is, suppose we deleted the code that modifies them,
and put in the correct contents when those data structures
are first created.)  Would we still have the problem of
pure pointing to impure which gets GC'd?

In other words, once we have fixed the specific bug we know about,
which involves modification of pure objects, do we still have a
problem?
