Struct swiss_army_knife::hardware_optimized_spin_lock::IntelHardwareOptimizedLockSpinLock

pub struct IntelHardwareOptimizedLockSpinLock(_);

An efficient, CAS-free unfair spin lock that uses an atomic exchange and only requires one byte of memory.

Uses Intel TSX Hardware Lock Elision (which should be backwards compatible) to create a spin lock. Inspiration from https://github.com/cyfdecyf/spinlock, https://software.intel.com/en-us/articles/tsx-anti-patterns-in-lock-elision-code and http://locklessinc.com/articles/locks/.
