Very good idea.  http://bugs.python.org/issue12850

The extension module, called 'stm' for now, is designed as an
independent 3rd-party extension module.  It should at this point not
be included in the stdlib; for one thing, it needs some more testing
than my quick one-page hacks, and we need to seriously look at the
deadlock issues mentioned here.  But the patch to ceval.c above looks
rather straightforward to me and could, if no subtle issue is found,
be included in the standard CPython.


A bientôt,

Armin.
