与此形成对比的是，无锁定算法要求仅某个线程总是执行操作。
By contrast, a lock-free algorithm requires only that some thread always make progress.
该分配被认为是无争用锁定操作中最大的可变开销。
The allocation is considered the largest variable cost in an uncontested lock operation.
如果已知锁定是无争用的但是难以避免或删除同步指令，则对这些锁定花费一点小的确定的开销不失为明智的做法。
It can be desirable to have a small and deterministic cost for locking that is known to be uncontested but where synchronization directives are hard to avoid or remove.

Smartphone keys will be locked automatically at slider closing (without confirmation message).
本文介绍了一种用一阶或二阶无静差系统来锁定、倍频和跟踪的新型环路。
