The shell in Wing is based on our debugger, which ends up allocating support
structures for every code object, among other things.  I will take a look
at it but suspect it's mostly unavoidable overhead.

Of course we may want to change things so the shell is not based on the debugger,
or at least doesn't install all the machinery until the user wants to actually
debug the code there (which currently isn't possible, but really should be).
