Introduction

We can simply protect a shared resource by a lock. But the performance is not good because each reader should run one-by-one.

A Reader-Writer lock can improve the performance by let readers running simultaneously.

By the way, a writer should wait until all readers done. In a frequently read situation, a new reader after the writer can also increase the read count, let read count never decrease to 0. This will starve writer.

RwLock:

1. Let readers running simultaneously.
2. Exclude "multiple readers" and each writer.
3. provide a flag "write_first" to prevent starve writer.
