[Digikam-users] Can "Sharpen" be parallelized?

the "sharpen" feature with the refocus option takes - even when using a
3.4 GHz CPU - very long on a 16 Mpix raw image (Nikon D800). I have a 6
cores CPU but only one core is being used on "sharpen". Wouldn't it be
possible to parallelize sharpen such that all 6 cores could work at the
same time on different domains of the image such that the turnaround
time would be sped up by a factor of 6 ?
