Independent of the type of lock chosen above, locks could be classified by what happens when the lock strategy prevents progress of a thread. Most locking designs block the execution of the thread requesting the lock until it can be allowed to access the locked resource. A spinlock is a lock where the thread waits until the lock becomes available. It is very efficient if threads are just likely to be blocked for a short period of time, as it avoids the overhead of operating system process re-scheduling. It is wasteful if the lock is held for a long time.
