由于任意工作量的一个线程或进程的上下文切换涉及到的开销较大，小粒度级的系统往往效率低下且遭遇低性能问题。
Due to the overhead involved in context switching to a thread or process for any amount of work, systems with small-scope granularity are often inefficient and suffer from low performance.
现代操作系统通常在进程调度方面表现得很出色，从而最大程度减少了上下文切换。
Modern operating systems generally do an excellent job of process scheduling, which minimizes context switching.
mkdir系统调用用来创建这个上下文，用户进程然后可以打开这个目录中相关的文件。
The mkdir system call creates the context, and the user process can subsequently open the associated files inside that directory.
