Struct vasi_sync::scmutex::SelfContainedMutex

#[repr(C)]
pub struct SelfContainedMutex<T> { /* private fields */ }

Simple mutex that is suitable for use in shared memory:

• It has a fixed layout (repr(C))
• It’s self-contained; e.g. isn’t boxed and doesn’t refer to global lock-state in this process’s address space.
• Works across processes (e.g. doesn’t use FUTEX_PRIVATE_FLAG)

Performance is optimized primarily for low-contention scenarios.
