Perhaps if you shared fftw_plan across all objects that use the same 
block size, you'd save clicks? Perhaps that just loading the fftw class 
that you are using could prepare plans for several common block sizes? For 
example every power-of-two from 64 to 4096.

I doubt that Miller tried FFTW3...?
