※ 引述《work76 (work)》之铭言：
: describe the action taken by a kernel to context switch between the floowing
: and point out the difference among them:
: 1.processes
: 2.user-level threads
: 3.kernel-level threads
proccesses 间的切换 : PCB 的操作
user-level threads 间的切换 : 跟 kernel 没关
kernel-level threads 间的切换 : thread data structure 跟 CPU registers 操作
