Hi,
Actually, not even one month ago, Intel announced that its processors
will offer Hardware Transactional Memory in 2013:

So yes, obviously, it's going to happen.
A bientôt,
Armin.
This is very interesting, cheers for the link.

If that's the question you want an answer to, it would have been better
had you listed the efforts that you are already aware of. If you really

That's correct.

Armin, thanks for weighing in on this. I'm keen to see a CPython
making use of STM, maybe I'll give it a try over Christmas break. I'm
willing to take the single threaded performance hit, as I have several
applications that degrade due to significant contention with the GIL.
The other benefits of
Given GCC's announcement that Intel's STM will be an extension for C
and C++ in GCC 4.7, what does this mean for Python, and the GIL?
I've seen efforts made to make STM available as a context, and for use
in user code. I've also read about the old attempts way back that
attempted to use finer

I did see this, I'm not convinced it's only relevant to PyPy.

Azul has been using hardware transactional memory on their custom CPUs (and
likely STM in their current x86 virtual machine based products) to great
effect for their massively parallel Java VM (700+ cpu cores and gobs of
ram) for over 4 years. I'll leave it to the reader to do the relevant

Explicit STM doesn't seem particularly useful for a language that
doesn't expose raw memory in its normal usage.
