Processing is a Python package which supports the spawning of processes
using the API of the standard library's threading module. Features include:
* Objects can be transferred between processes using pipes or
multi-producer/multi-consumer queues.
* Objects can be shared between processes using a server process or
(for simple data) shared memory.
* Equivalents of all the synchronization primitives in threading
are available.
* A Pool class makes it easy to submit tasks to a pool of worker
processes.
