SharedBuffer uses RefCounted, an implementation that works only on a single thread, as opposed to the slower CrossThreadRefCounted.

We can test your guess about the memory problems being a thread-safety issue by adding assertions that check ref and deref are called only on one thread. Those would be extremely valuable. Someone was working on assertions of that type a while back, but I don’t think we successfully landed them.
