psycopg2 is implemented in a fork of mine: http://bitbucket.org/alex_gaynor/pypy-postgresql/ it requires compiling yourself, but works nicely (I was told by someone that this brought their script's time from 2 minutes to 8 seconds). As of last test it passes all Django tests. What's the current standard RabbitMQ lib? I didn't realize it was a c-extension (hell I've used it myself and never noticed).

Well the most used one is Celery. It depends on multiprocessing which blew up on me the last time I tried it in PyPy.

But.... I just tried "import multiprocessing" in PyPy 1.5 and it worked! Is this all part of the C-API compatability layer? Does that mean Cython code may soon work in PyPy too (that's my pony feature)?

RabbitMQ should work under PyPy currently then, all of its dependencies purport to be pure python. ---

Another RabbitMQ lib is Rabbitmq-c which is direct wrapping around librabbitmq-c. It ecks out extra performance vs pure python rabbitmq, but mostly it isn't needed.

Nope, multiprocessing was added to the Python standard library in 2.6, our previous releases implemented python 2.5, 1.5 implements 2.7, so it now includes multiprocessing.

That's good news! Guess it's time to remove the mechanism in Celery that disables the multiprocessing pool when running under PyPy.
