That's weird. Preemption should happen every few dozen milliseconds unless you've purposely increased the preemption delay.
To me, it smells like a call into a C extension which isn't releasing the GIL before starting a time-consuming operation. After getting bitten by this a couple of times, I now make sure to release the GIL as part of my SWIG wrapper (since the code I'm wrapping knows nothing of Python, and sure as heck doesn't need to be holding the GIL!).
Cheers, Nick.
