 // |PlatformSharedBuffer| is an interface for a thread-safe, ref-counted wrapper
 // around OS-specific shared memory. It has the following features:
 //   - A |PlatformSharedBuffer| simply represents a piece of shared memory that
 //     *may* be mapped and *may* be shared to another process.
 //   - A single |PlatformSharedBuffer| may be mapped multiple times. The
 //     lifetime of the mapping (owned by |PlatformSharedBufferMapping|) is
 //     separate from the lifetime of the |PlatformSharedBuffer|.
