Thanks Sturla and all the others for this very interesting discussion!

Specifically on this point, playing the devil's advocate, one could
argue that using java we could also migrate the offending routine to
C. Is there an element to argue that the Python/C mix is simpler or
more powerful than the same for java/C?

I saw also somewhere the argument that python tools containing C/C++
routines like numpy and wxpython are more naturally or easily made for
python than for java. Is that really true?
