Without any thread having a reference to it, the payload's reference
count is 1. The reading thread above increments the counter when making
a local copy, but the writing thread decrements the counter when
assigning Container.init. If both run concurrently, with the sequence 1
to 3 above, trouble is inevitable.
Right, but isn't that an issue with having ANY shared variable that isn't
protected by a lock?
I was thinking you had passed the pointer in via a message or something.
