Hi David, Roland, and Erik,

yes, I expressed interest in working on the FFT parallelization,
however, right now I have started to implement an additional pull
option. I cannot say when exactly I would have time for the FFT - so
please go ahead! I'm shure there are plenty of things to work on so that
I will simply choose something else then.

Thanks for asking!
