    ...generator. The Mersenne Twister algorithm is implemented in C, threadsafe, faster than the previous generator, has an astronomically large period (2**19937-1), creates random floats to full 53-bit precision, and may be the most widely tested random number generator in existence. The random.jumpahead(n) method has different semantics for the new generator. Instead of jumping n steps ahead, it uses n and the existing state to create a new state. This means that jumpahead() continues to support ...

We only had to write, in Python, our custom RPC protocol, because XML-RPC (and it's Python implementation) proved to be too slow and processor-intensive. Scalability was an issue that we solved at design time, but Python let us create programming constructs like the transparent distributed RPC system and extensible API system. In regard to stability, we think that Python's great exception handling mechanism gave us an enormous advantage. Our coding error...
