当一个进程对这个文件执行spu_run ioctl调用时，这个进程本身就会被挂起，而SPU则会开始执行ioctl参数所指向的指令。

When a process performs the SPU_RUN ioctl on this file, the process itself will be suspended and the SPU starts executing at the instruction pointed to by the ioctl argument.

但是，将解密后的 AuthBundle 存储到实例变量（_credentials）中，则是个错误的做法，在连接器被挂起以及应用服务器将其写入磁盘的过程中，未经身份验证的人就可能进入临时文件中检索凭证。

When the connector is passivated and the application server writes it to disk, an unauthorized party could go into the temporary file and retrieve the credentials.

在具有多个文件的场景中，可以想象到，挂起的更改可能不会与修复关键错误所必需的更改相冲突。

In a scenario with multiple files, you can imagine that the suspended changes might not have conflicted with those necessary to fix the critical bug.
