Detailed Description

The singleton pattern we use here is tricky because we have to ensure:

RegisterStream() succeeds, even if called before main() enters and before any constructor run in this file.
UnregisterStream() succeeds, whether or not FlushStreams() has been called.
All memory allocated with new is deleted properly before program exit.

This is why we go through all the painful hoops below.
