52 .Ss Spin Mutexes
53 Spin mutexes are a variation of basic mutexes; the main difference between
54 the two is that spin mutexes never block.
55 Instead, they spin while waiting for the lock to be released.
56 To avoid deadlock, a thread that holds a spin mutex must never yield its CPU.
57 Unlike ordinary mutexes, spin mutexes disable interrupts when acquired.
60 Spin mutexes should be used only when absolutely necessary,
