Multiple simultaneous Python interpreters

[White Flame (aka David Holz)]

Hi, I'm evaluating Python as a scripting language in a project I'm defining.
Is there any way to encapsulate the interpreter so that multiple ones can
exist in a program?  Some would be in their own thread, some would get
called from the same one sequentially.  However, in the docs I've read,
there's always just been one "global" interpreter.  Not very OO for an OO
language. ;-)
