spinlock

This is a lock that can be held by only one thread of execution at a time. An attempt to acquire the lock by another thread of execution makes the latter loop until the lock is released.

How does it handle the case when two threads try to acquire the lock exactly the same time?

I think this question also applies to various of other mutex implementation.
