Some programs may wish to bind a KSE (pedantically speaking, a KSEG is bound) to a particular processor in order to improve cache locality, or to tighten the bounds on a real-time task. Bound KSEs are run only on one CPU, unless priority inheritance forces it to be run on another CPU in order to avoid deadlock due to priority inversion.

一些程序可能希望把KSE绑定在一个单独的CPU上来提高缓存的击中率，或是让实时任务更严密，被绑定的KSE只运行在一个CPU上，除非在优先级倒置时，为了避免死锁，优先级继承迫使它运行在另一个CPU上。
