> Issue Type: Bug

> Affects Versions: NG alpha 2

> The memory channel isn't thread safe as a couple of parallel transactions can
> commit/rollback each others entries if called in the wrong order.
> I'm attaching a unit test I made that demonstrates it using a cyclicbarrier
> to force the event order that causes the precondition to fail.
