-// ***** LocklessUpdater
-
-// For single producer cases where you only care about the most recent update, not
-// necessarily getting every one that happens (vsync timing, SensorFusion updates).
-//
-// This is multiple consumer safe, but is currently only used with a single consumer.
-//
-// The SlotType can be the same as T, but should probably be a larger fixed size.
-// This allows for forward compatibility when the updater is shared between processes.
-
-// FIXME: ExchangeAdd_Sync() should be replaced with a portable read-only primitive,
-// so that the lockless pose state can be read-only on remote processes and to reduce
-// false sharing between processes and improve performance.
