Worth thinking about, but paralellizing join would be quite
complicated.
In the meantime, I think that you should find that the speed
improvement for join in current CSV is very substantial and makes it
feasible to use join in a loop for multiple series (even with big
data) without taking forever.
Mmmhh, I couldn't figure out any substantial
speed improvement on my old
PC here. But I did some testing on more modern machines, and actually it
seems to works quite reasonable there. I guess my machine is just too
slow to expect some faster processing :-)
