* Atomic operations.
*
* IMPORTANT:
* If you are not an expert in concurrent lockless programming, you should
* only be using the atomic lock and reference counting functions in this
* file. In all other cases you should be protecting your data structures
* with full mutexes.
*
* The list of "safe" functions to use are:
* SDL_AtomicLock()
* SDL_AtomicUnlock()
* SDL_AtomicIncRef()
* SDL_AtomicDecRef()
*
* Seriously, here be dragons!
* ^^^^^^^^^^^^^^^^^^^^^^^^^^^
*
* You can find out a little more about lockless programming and the
* subtle issues that can arise here:
* http://msdn.microsoft.com/en-us/library/ee418650%28v=vs.85%29.aspx
*
* There's also lots of good information here:
* http://www.1024cores.net/home/lock-free-algorithms
* http://preshing.com/
*
* These operations may or may not actually be implemented using
* processor specific atomic operations. When possible they are
* implemented as true processor specific atomic operations. When that
* is not possible the are implemented using locks that *do* use the
* available atomic operations.
*
* All of the atomic operations that modify memory are full memory barriers.

* would insert a release barrier between writing the data and the flag,
