* Proper semantics for Java-style memory, for both ``volatile`` and regular
shared variables. (`Java Specification

+ <http://docs.oracle.com/javase/specs/jls/se8/html/jls-17.html>`_)
* gcc-compatible ``__sync_*`` builtins. (`Description

* Other scenarios with atomic semantics, including ``static`` variables with
non-trivial constructors in C++.
