ForkJoinPool.acquirePlock介绍

[英]Acquires the plock lock to protect worker array and related updates. This method is called only if an initial CAS on plock fails. This acts as a spinlock for normal cases, but falls back to builtin monitor to block when (rarely) needed. This would be a terrible idea for a highly contended lock, but works fine as a more conservative alternative to a pure spinlock.
[中]获取plock锁以保护工作阵列和相关更新。只有当plock上的初始CAS失败时，才会调用此方法。这在正常情况下起到旋转锁的作用，但在（很少）需要时会退回到内置监视器来阻止。对于高度竞争的锁来说，这是一个糟糕的想法，但作为纯自旋锁的一个更保守的替代方案，它可以很好地工作。
