New Revision: 17625

Modified:
   pypy/dist/pypy/translator/backendopt/inline.py
Log:
changed the threshold of inlining to 32.4 to prevend us from inlining
too much of rlist. Best result, so far.
But I'm not sure wether we should try the old threshold again
after reverting the _ll_list_resize change?
