Can you expand a bit? Are you trying to disable threads at compile-time or at run-time? Which threaded functionality are you trying to disable? Are you using numpy as a computational library with multiple threads making calls into its functions? I think NPY_ALLOW_THREADS is for interacting with the GIL, but I have not played with it much.
