Fix %timeit for slow functions, by Prabhu Ramachandran....

Fix %timeit for slow functions, by Prabhu Ramachandran. From his submission on the list: Lets say you have a function that takes 2 seconds to evaluate. With the original code you are going to run that function 10 times regardless of the fact that it already takes 2 seconds and with the original code, timing this will take at least 60 seconds (with repeat=3) which is way too much.
