Armin, Sarah and I are restarting our work on CSP, and extending to creating actors and a dataflow library. It would be good to make this work on Jython, IronPython and PyPy as well as CPython. However we want to get away from a reliance on multiprocessing since it is rather heavyweight for the sort of parallelism we are after. STM as an infrastructure layer in PyPy and CPython would get us away from the GIL and allow for using Python threads bound to kernel threads to allow a single Python process to allow us to create lighweight processes (no application level shared memory).
Is the STM variant of PyPy and/or CPython in any form of usable state? If so then we can investigate building from source for ourselves so as to use it as a foundation for building the higher abstraction parallelism for applications programmers.
