I only used it for experimentation so far, but I abondoned it, after I learned, that only one worker can be the active user of a SharedArrayBuffer. So they cannot be shared at the same time? Sharing seems to mean, now A uses it, than gives control back, via the main thread, then B uses it, etc

(but I hope I missunderstood something there)

But I need many threads to access the same data, at the same time (readonly, so no racecondition).
