Well, I'm a huge Python fan myself, but multiprocessing is not really
a solution as much as it is a workaround. Python as a language has no
problem with multithreading and multicore support and has all
primitives to do conventional shared-state parallelism. However, the
most popular /implementation/ of Python sacrifies this for
performance, it has nothing to do with the language itself.

Stackless Python is an interesting implementation of the CSP+channels
paradigm though. It has been quite successfully used for a few large

Of course scalability is a "real" problem, ask anyone who runs a big
website. I don't see how RESTful design simply removes that problem.
