Tested the modified _csv.py and it produces no measurable speedup on latest 
nightly, so I assume either the JIT has been improved and the modifications are 
no longer necessary, or the worthwhile modifications were incorporated in some 
form and not noted here.

Current relative timings to CPython 2.7.3 are as you have in "After changes to 
csv module's reader": about 1.3-1.5x CPython.
