Embedding Python. But not so easy.

Right now I am in a project writing a Simulation engine, and we are right now
in the process of evaluating a script engine.
The basic principle is a C++ engine simulating the environment and scriptable
agents interacting with the environment.
But the current design has a special requirement to that scriptability and my
current knowledge of the API of Python isolated two problems
1) Threads: the simulation is going to be run in a very parallel environment
with several CPUs and http://docs.python.org/c-api/init.html#thread-state-and-
the-global-interpreter-lock there is a global lock mentioned. Does that mean
that the python code can not benefit from this ?
2) The script has to hand back control to the C++ framework without increasing
the C execution stack. and be able to resume the execution at a later point.
I try some pseudo code here to explain
ctx = new ExecutionContext();
# Here the execution is suspended und control handed back to the C++ code
I hope that makes it clear. I did not see a way to implement this with the
I am hoping to be proven wrong
Thanks in advance
