It's quite easy to release the GIL while you are running non-python code.[1] Just be sure that if you touch the Python API that you reaquire the GIL.[2]

When you say HTTP API, does that mean you had C++ http server, C++ http client, Python http server and Python http client?

Good question: In this case C++ was the server, and Python (via urllib2) was the client.

Out of curiosity, why didn't you fork and use a pipe?

We're running on Windows, and fork isn't available there. Also, in this case AFAIK fork doesn't really apply, as we wanted to start the C++ and Python servers completely separately.
