[issue31654] ctypes should support atomic operations

[Antoine Pitrou]

Antoine Pitrou <pitrou at free.fr> added the comment:

Note that if there is already a C API to perform atomic ops, you can simply use ctypes to invoke that API.  Unfortunately, the aforementioned GCC builtins seem to be only available as intrinsics (at least I couldn't find a shared library that exposes the __atomic_* functions on my system).
