Reduce the overhead of acquiring a lock by first testing the locking criterion (the 'lock hint') in an unsafe manner; only if that succeeds does the actual locking logic proceed.
Warning
Can be unsafe when implemented in some language/hardware combinations. It can therefore sometimes be considered an anti-pattern.
