As I understand it, 'rexec' is only safe if you don't pass in any unsafe
objects.  Classes, functions, and class instances are all generally unsafe.
What you need is 'Bastion', which (as I understand it) is a safe wrapper
around an unsafe object.  I assume 'Bastion' is implemented as a C extension
type, which gives it data hiding capabilities that Python class instances
don't have.
