## Detailed Description

This represents a reader-writer lock.

It is similar to a Mutex in that it allows multiple threads to coordinate access to a shared resource.

The difference to a mutex is that a reader-writer lock discriminates between read-only ('reader') and full ('writer') access. While only one thread at a time is allowed write access (by holding the 'writer' lock via writer_lock()), multiple threads can gain simultaneous read-only access (by holding the 'reader' lock via reader_lock()).
