wip/py-csp 0.9.2 NetBSD

The PyCSP project is an on-going project to bring CSP (communicating sequential processes) to Python.

PyCSP Provides:

* A flexible CSP library for Python; * Synchronous communication; * Buffered channels; * Multiple process types such as, greenlets, threads, processes and remote processes; * Both input and output guards supported in external choice (Alts); * A single any-to-any channel type; * Mobile channel-ends; * Retire and poison signals for shutting down networks nicely; * A channel which can communicate using inter-process communication as well as sockets; * A PyCSP providing local and distributed communication using only standard python modules bundled with CPython; * NAT traversal; * Tracing PyCSP executions to a log file, for later visualisation;

This is the "complete" version of PyCSP as opposed to the "base" version.
