Right, this is a concern that I brought up with Richard when we 
originally chatted about this a long time back (I think at JavaOne 
2014). I haven't had a chance yet to look at the current proposal but it 
would minimally need a big warning as it would be too easy to cause 
deadlocks and other issues when not used correctly.
