We're aware of it, and it will definitely happen before we do any sort
of release.

Amaury or Benjamin could better say.

The last thing Jason Creighton wrote on the subject that I can find, from Aug 13, was: "...the bottom line is that the main goal of my GSoC was accomplished: A working 64-bit PyPy JIT. Hopefully I'll be able to complete asmgcc-64, and make the JIT even faster..."

>>> So it sounds like he (or someone) DID get the Linux version of it working. Has it been merged into the trunk? Does it seem stable? You say: "Expect this to be a major selling point for the next PyPy release :-)"  Do you have an estimate of when that'll come out?

I see "r77223 - in  pypy/branch/fast-forward/pypy/module/_multiprocessing: . test" in the svn commit log, dated Tuesday of this week (http://permalink.gmane.org/gmane.comp.python.pypy.cvs/29865)... I'm hoping that means it's going to be supported soon? That would be really great.
