--- Comment #6 from Dan Gohman <dan433584 at gmail.com> ---
The WebAssembly CG has now decided to change the WebAssembly semantics.

https://github.com/WebAssembly/threads/issues/19#issuecomment-306625084

and the guidance is now that C++ implementations may now treat 8-bit, 16-bit,
32-bit, and 64-bit atomics as "lock free" under C++'s terminology.
Consequently, the patch referenced above is no longer needed.
