Sure, but then they shout all over how safe they are. They got rid of the safeties pretty late, when they ripped out their GC, but kept their false promises all over.

No, that's common knowledge. I fixed concurrency safety by forbidding blocking IO. Others also. Maybe there are other ways, but never heard of other ways.

This seems like a non-sequitur to me? The presence/absence of a GC is not dispositive with respect to determining "safety", especially when the GC itself involves unsafe code.

		Have you ever seen a GC system with memory unsafeties? I cannot remember any

Huh? It doesn't follow that forbidding blocking IO is either necessary or sufficient for concurrency safety, at least under any definition of "safety" I can imagine. What do you mean? You mean async-not-blocking-event-loop stuff? That's not the only way to do more than one IO at a time.
