We've recently had a discussion about more intelligent timeit commands 
and timing objects in Python/Sage.  People here might find the 
discussion interesting, and it might also be interesting to collaborate 
on code.  The basic idea was a much smarter timeit command that uses 
more intelligent statistics and presents a much more comprehensive look 
at the timing information.

Here is the discussion:

Here is our ticket tracking the issue: 
http://trac.sagemath.org/sage_trac/ticket/12168

Here are some examples of the analysis: http://sagenb.org/home/pub/3857/

I've CCd the sage-devel list as well, which is where our discussion 
happened.

Thanks,
