[SciPy-user] parallel usage of fftw

I've read at
that getting fftw to use multiple threads to speed up performance on SMP
machines is quite easy to initiate.
Has anyone used tried this?
I haven't ever used fftw without scipy, but if there were some way to
easily implement a python interface such that fftw_init_threads(),
fftw_plan_with_nthreads(), and fftw_cleanup_threads() could be called,
it would be really cool.
I'm having a bit of a time trying to figure out how fftpack is married
to fftw ... maybe I should just try calling those functions with ctypes?
Any input would be greatly appreciated.
