Detailed Description

Spin-lock for thread synchronization.

This works like Mutex but does a busy wait (no sleep) while waiting for a lock
This consumes CPU and can be more efficient than Mutex under certain conditions, where wasting CPU is acceptable
- This also supports a less busy wait with SpinLock::SleepLock
Thread safe
See also: SleepLock
Caution: Only use if you're certain you understand the consequences, if in doubt use Mutex instead
