I used api-next as staging branch for patches which do not have anybody

Will merge that patches to master
It's fixing the deadlock issue reported by Carl where A is queueing to B
and B is queuing to A. The previous scheme relied on a statistical locking
strategy that was prone to stalls, especially on uniprocessor systems.
Your suggestion solves this issue and is also simpler and faster.

Enqueueing to ordered queues requires two locks (source and target
queues). Since any queue can be either source or target, queues do not
have a natural locking hierarchy. Create one by using the address of
