Hi all,

An update: now we can translate "--stm -O2", with a twist (the method
cache is disabled), and the timings are:

  1 thread: 2031ms
  2 threads: 1194ms
  4 threads: 840ms
  8 threads: 533ms

It's worth pointing out, because it's the first time I see a measure
(the last one) which is *faster* than the single-core, no-stm, no-jit
version.  We are not done yet, because CPython runs the same program
at 303ms.  But we're getting there :-)


A bientôt,

Armin.
