System: 8 core i7. OSX. Recent nightly.

* Changed xrange loop size to 10000000 instead of 100000. 
* real/user/sys times in seconds

               output file
          test.txt        /dev/null
CPython  6.9/4.2/0.8    4.0/4.0/0.01
pypy     7.4/2.4/0.6    2.4/2.4/0.06


Not sure that this is an actual pypy issue - maybe a filesystem dependent timing 
problem?
