Detailed Description

Allows multiple "reader" threads to obtain a lock simultaneously, but only one "writer" thread.

This implementation is currently just a wrapper for pthreads, which works on Linux/Mac/. This is available in C++17 as std::shared_mutex, but unfortunately we're using C++11.

Locking should be avoided in real-time audio threads.
