Peter,

I have read your paper referenced above and a few of the other papers 
dealing with atomic ops, but I failed to find a clear definition of what 
'acquire' and 'release' semantics are supposed to mean. Could you point 
me into the right direction, please? Also, in your paper you're 
referring to [intro.concur], where could I find this?

TIA,
Markus
