Good question.  You could use some of their ideas, or at least some of
the references, but maybe not the code.

No, my understanding is you choose the behaviour.  You can use
FFTW_MEASURE and it will actually search for the fastest way to
perform your fft, but you can instead use FFTW_ESTIMATE and it will
not introduce this overhead.
