-// SyncValue is a typed equivalent of sync/atomic.Value.

-
-// This uses a dumb mutex-based solution because
-//
-//  1. Performance is good enough, because in the fast-path mutexes
-//     use the same compare-and-swap as sync/atomic.Value; and because
-//     all of these methods are short we're unlikely to hit the
-//     mutex's slow path.
-//
-//  2. We could use sync/atomic.Pointer[T], which by itself would have
-//     the same performance characteristics as sync/atomic.Value but
-//     without the benefit of runtime_procPin()/runtime_procUnpin().
-//     We want to avoid that because it means we're doing an
-//     allocation for every store/swap; avoiding that is our whole
-//     reason for not just wraping sync/atomic.Value.  So then we'd
-//     want to use a SyncPool to reuse allocations; but (1) that adds
-//     more sync-overhead, and (2) it also gets trickier because we'd
-//     have to be careful about not adding a pointer back to the pool
-//     when load has grabbed the pointer but not yet dereferenced it.
