// Class : MutexSpinlockImpl
// Description : Uses Windows native calls to implement a mutex.
// Description : Uses a simple user-space spinlock to implement a
// mutex. It is usually not a good idea to use this
// implementation, unless you are building Panda for a
// specific application on a specific SMP machine, and
// you are confident that you have at least as many
// CPU's as you have threads.
