recursive acquire of GIL

[Paul]

Hi

I have seen this discussed already on the newgroup but
have not seen if the problem is solved

Using embedded python in c++ we use
PyEval_RestoreThread(context);
to acquire the GIL.

We then use swig to call back into c++ which again
calls out to python
Essentially we have
c++ -> python -> c++ -> python

The second RestoreThread uses a different python context of course.
However it hangs

PyEval_RestoreThread(context2);
is hanging.

We're using python 2.2.1

Has a solution to this been added to later versions?

Regards

Paul

I think PEP 311 solved this in 2.3:
