ringbuf.js

By a quick glance, yes, this is what I want: a channel to communicate between processes via a piece of shared memory, protected by a pair of futexes.

In my use case on I/O between WASM modules where data must be transferred as-is, the process must block on buffer overrun/underrun in a synchronous manner. Therefore a circular buffer is required. I could not find such a niche library written in JS, so I decided to bite the bullet and reinvent the wheel [2]. [1]: https://github.com/padenot/ringbuf.js [2]: https://github.com/andy0130tw/spsc
