I think that David said he kept the kissfft only because it was faster. The
kissfft however, uses twice as much memory, not being an in-place algorithm.

This can be easily changed in the code though, if a slower in-place is used
that still performs the task "fast enough" and you are running out of
memory.

He did do a lot of memory optimizations last year, as I recall.
