The timeit module was written by Tim Peters. Since then, others have 
contributed as well, but the basic recipe is his.

For those who don't know, Tim Peters, a.k.a. the timbot, is one of the 
old-time Python demigods. He is responsible for not one, but two, 
awesomely fast sort routines: the original list.sort() method was his, 
and then around Python 2.3 (I think) he re-wrote it using a new sort 
method which is even faster, added stability, and has fewer special 
cases than the previous version. This sort algorithm has since been 
adopted by Android and Java 7.
