[docs] typos in docs

Hello, I was reading in the multiprocessing module section today https://docs.python.org/2/library/multiprocessing.html#all-platforms and noticed a few minor errors: "Remember also that non-daemonic processes will be automatically be joined." That sentence has the word 'be' twice. The word wrap must have got somebody. Then a few lines later it says: "A fix here would be to swap the last two lines round (or simply remove the p.join() line)." Though most people probably understand this because 'round' is a slang-ish way to say 'around', we should probably change this to use the proper spelling.
