Read-Write Spinlocks

description

Implement spin locks which do minimal locking within this locker. These spin locks are not recursive. They cannot be embedded within each other. They also have write priority (as reading is done much more often--including when being pulsed or timing out after 6 seconds of locking & re-querying).
 
This is pretty easy, but recently I have been skipping steps, trying to implement policy based locking in one go. Current source, 3393, may get reverted back a few steps to something more stable (3393 also utilizes read-write spinlocks).

I hate race conditions : ). Getting close, but spinlocks have an instance where upgrading read to write lock causes infinite loop.
