Ah you're right.  ... but subtract GC, and just have the buffer
reallocated in thread B, and guess what happens?[1]

So I didn't get it right, and you miss things, too.  "Threading is
hard, and then you deadlock."

What was the application that makes general threading so attractive,
again?

I have to wonder if it might not be a better idea to develop ways to
share specified data across processes cheaply, eg, via shared memory.
