Very cool! I see that SharedArrayBuffers are enabled again, after they were disable due to spectre!?

I have previously tinkered with ffmpeg in the browser and implemented a workaround[1] for the (then) missing pthread support. It turned out quite clunky, but worked.

Yeah, SharedArrayBuffers have been back and forth!

- First they were disabled due to Spectre. - Chrome reenabled them. - New HTTP headers were added for cross-origin resource partitioning. - FF/Chrome are both requiring those headers (FF now, Chrome next month)

That's awesome that you've played around with this, too. It was quite a bit of fun :)
