A simple spin-lock class that can be used as a simple, low-overhead mutex for uncontended situations.
Note that unlike a CriticalSection, this type of lock is not re-entrant, and may be less efficient when used in a highly contended situation, but it's very small and requires almost no initialisation. It's most appropriate for simple situations where you're only going to hold the lock for a very brief time.

Acquires the lock. This will block until the lock has been successfully acquired by this thread. Note that a SpinLock is NOT re-entrant, and is not smart enough to know whether the caller thread already has the lock - so if a thread tries to acquire a lock that it already holds, this method will never return!
It's strongly recommended that you never call this method directly - instead use the ScopedLockType class to manage the locking using an RAII pattern instead.
