Comment:

 There is no spin_lock implementation in Boost.Atomic. There are probably
 spin lock implementations in other libraries, but I don't think any of
 them is public. You'll have to specify what particular implementation you
 are interested in.

 In general though, spin locks tend to provide no guarantees about fairness
 or priority support. You typically have to use special mutex types that
 provide these guarantees.
