New Revision: 13671

Modified:
   pypy/dist/pypy/translator/test/rpystone.py
Log:
removed range, because it made measures very flaky.
On my machine, I get around a factor of 40 for slow mode
and some unbelievable 1600 for fast mode.
The latter is probably due to code removal.
But that's fine, too.

For real testing, we should use something that produces
a result that cannot be ignored by optimizatiion, tho.
