Tcl objects may reference other objects.  Think of a list.  So it's
not enough to copy an object's internal rep, you need to follow the
references and do a deep-copy.  That's real ugly because then you need
to know the details of each object's internal rep.

What happens when you come accross an object you don't know about?

Punt, I guess: stringify it.

It may or may not be worth while adding per-interp caches to the cache
code, but I'm pretty sure ADP is the way to go for Tcl page caching.
