I don't think IronPython should support multiprocessing, personally.
While there are a few things within it that probably make sense
(managers and the like) does it really make a ton of sense to run
multiple iron python VMs from a single parent?

The same applies (in the case of multiprocessing) to Jython - a single
JVM forking multiple JVMs doesn't necessarily make sense when you have
perfectly functional threads. Then again, this depends on your

When splitting out the stdlib was discussed at the language summit
last year, this was discussed, and at the time a few people suggested
allowing some stdlib modules to be marked at "cpython-only" - this
means other implementations could omit/skip those modules (and not
ship them).
