k--; // 剩余删除名额减1（关键：控制删除位数，保证保留足够长度）
The approaches differ in where they draw the boundary. Namespaces use the same kernel but restrict visibility. Seccomp uses the same kernel but restricts the allowed syscall set. Projects like gVisor use a completely separate user-space kernel and make minimal host syscalls. MicroVMs provide a dedicated guest kernel and a hardware-enforced boundary. Finally, WebAssembly provides no kernel access at all, relying instead on explicit capability imports. Each step is a qualitatively different boundary, not just a stronger version of the same thing.，更多细节参见safew官方版本下载

Web streams are complex for users and implementers alike. The problems with the spec aren't bugs. They emerge from using the API exactly as designed. They aren't issues that can be fixed solely through incremental improvements. They're consequences of fundamental design choices. To improve things we need different foundations.
