// Address arbiters are an underlying kernel synchronization object that can be created/used via
// supervisor calls (SVCs). They function as sort of a global lock. Typically, games/other CTR
// applications use them as an underlying mechanism to implement thread-safe barriers, events, and
// semphores.
