Detailed Description

Locking class to ensure exclusive access to output streams.

The class is intended to be used in a "locking is creation" design pattern. On creation an exclusive lock is optained, and on destruction the lock is released.

Uses a recursive mutex, i.e. does not distinguish reads/writes but my be called multiple times by the same thread without blocking.

Class is inlined for performance reasons.
