I've attempted to run it (not with this latest release yet though) and it appeared as if calling a numpy function essentially disabled the JIT for that function, which was not acceptable for us at that point. What did seem to help curiously was wrapping the numpy function in a python function and then calling that, which seemed to prevent the JIT being disabled in the calling function.
