Just saw the "take vs. indexing" speed thing. To get it quite right, I
think you probably need to create a new mapiter (after all, take is not
ideal since it requires contiguity - though I guess it could be used as
a special case). Its only half related but this might be interesting if
someone wants to look into it:

It does some smaller (but binary incompatible) tweaks to mapiter too,
though the speedup there is not nearly as big as should be possible (and
some fast special cases are not active). Mostly its a start of a
possible rewrite of the indexing machinery, but since the current
mapiter is rather organically interwoven with indexing...

Only a note, I would like to see it, but I doubt its a one day
project :).

PS: Wondering about visiting EuroScipy (if my schedule works out), if
some of you are there, it would be something I could imagine working on
then (until then, I don't have any time).
