I haven't done any embedding, but from what I understand the issue is
mainly that the Python stack is intertwined with the C stack.
Stackless Python would probably be safer for this because it stores
the Python stack separately on the C heap, so as long as it can switch
between different Python stacks, it can have different interpreters
(probably even allowing for shared globals, etc).
